Johnson / Evinrude carburettor service
In this video I remove the carburettor from my Johnson 30 HP outboard, clean it and install a service kit. This includes replacing the float, needle and seat and all seals.

Dangar Marine thank you for this video. It was EXTREMELY INSTRUMENTAL in me rebuilding the carbs on a 1985 Johnson 60hp. I am by no means a mechanic, but I literally could NOT have done it without your video. I can't thank you enough... Who knows how much $$$ you saved me. Keep up the great videos!!!

Used this to Rebuild carburetor x 2 ,55 evinrude commercial . Put it in the water yesterday 👌 this guys a legend 👍
Quick tip for tools to work on Carbs with. Gunsmith screw driver/tools sets are great for working on sensitive brass parts like Carb Jets. The screwdriver bits are designed differently than normal screwdrivers... normal screwdriver flat head bits are tapered, Gunsmith flat heads have an even thickness shaft so are less likely skip out of the slot and damage the soft brass or other screws that hold the Carb together. Also, these sets (not advertising for them but the one I have is an 89 piece set from Wheeler Engineering) offer a lot of bit size choices so you can find the exact bit that fits snug and is correct width to fit into whatever Jet/screw you need and helps to prevent damage to them. Thanks for your videos, they have been very helpful! Watched your other videos on Carb tuning and helped me get my work boat back to working order and working quicker than if I had to go to a mechanic, thanks a lot!

Hey Martin, great tip about the screwdrivers, I'll check them out.
I've been playing with all mechanical things since I could walk and I'm so grateful for doing what you do mate I've learnt so much
Thank you Stu, really help me fix up my old Johnson 25hp after it flatlined. Your videos are so helpful.
Hey Danger, I really appreciate the step by step. My Johnson 25hp stalls after I power down when arriving to dock. One marina just cleaned the carb but it still does the same thing. I opened up the fuel pump like in your video and discovered the same issues, broken cap and o-ring. Thanks for you input. Cheers
Take a photo of what you're dismantling as this helps when putting complex parts back together. If you are leaving the job for a couple of days its wise to put things back together hand tight. Stu your videos are great. Thanks for sharing your knowledge.

Excellent video! I bought a used Johnson 25hp outboard with electric start. It ran terribly! Decided to rebuild the carb and noticed someone had installed the float up side down! It was harder removing the starter to access the carb nut than it was rebuilding the carb! Thanks for a great video.
Great video. I have a request, could you make a video about symptoms. Like you'll know your carb needs cleaning if....or your float needs adjusted if .... Thanks for all the helpful content.

Awesome video Stu. I bought an Evinrude 30hp last week, it ran fine for the 3hr cruise home but now has a rough idle I suspect from picking up crud from the bottom of the tank (it got choppy 20minutes from home) first thing to do is is clean the carb (and tank, filter, plugs etc etc) but atleast now I have a comprehensive guide as to what I'm doing.
This video is going to be my tutor through the process this coming weekend. I have a 78 35hp Johnson with the same parts number. Thanks very much for this video. I’ll be filming a bit of it and reference this video.

Yes, back in 78 the engine HP was rated at the flywheel. This engine is around a 1993 or so that this guy is working on, and by then they rated it at the propshaft. Since about 5hp is lost between the flywheel and the propshaft, a 35 in 1978 is the same engine as a 30 in 1993 because your 78 only has about 30 propshaft horsepower.
Thanks so much, was rebuilding my carb and never would have seen the main jet on the bottom of the bowl if not for your vid!
love your work stu, especially with a brewskie next to it
Nice video and work. Do you know what the 2 numbers inside carb represent? Located just below emulsion tube, one number above the other. 334 375. A different carb that looks identical has 332, 562. I’m trying a different eBay carb on my 28spl. Thank you.

Only thing I would add is on older carbs, check the butterfly shaft for excessive play before you order any parts. Most of the butterfly shafts run 'plain bearing' in the body of the carb and once they get to a loose fit the carb is often considered 'worn out. No one sells a bush kit for these carbs, but any decent machinist can make a set of bushes and ream the carb body to fit the bushes and so return the butterfly shaft to a decent air tight seal.

I’ve been working on a 1984 Evinrude 35 hp I’ve been thru the fuel system twice rebuilt the fuel pump carb looked like someone had already been thru it good compression and appears good spark on cranking it will start and run for about 20 seconds and die float bowl is full of fuel I don’t know maybe it’s running to rich but it will only start after I hit the primer I’d say it’s starving for fuel or it’s losing spark
great videos keep it up thanks glad im in fresh water only
That was the cleanest carburetor bowel I have ever seen. Now in my world the pivot pin has corrosion on it and when you try to push it out the tower that holds it snaps off and you have to buy another carburetor anyway.

Videos really been helping me out find a problem with my 1990 johnson 28 spl..i think im having a carb problem..itll start up run but onece i put it in forward gear then try to accelerate it dies..any pointers??
I have a 1969 Johnson outboard 2 stroke it runs good but it hesitate off idle to going full throttle. Should I just rebuild the carburetor or just clean the inside out or just the fuel bowl? That's again Kyle
Should mention when adjusting the float not to use the needle and seat to bend the float higher. It is very tempting to just jam it against the seat to bend upwards.
@DangarMarine
6 жыл бұрын
Yes indeed. I find holding the float up off the seat a bit helps with that but a good point well worth mentioning.
Ever make a video tuning the carb?
First off. Very good video. Quality is top notch. Did I miss the part where you replaced the freeze plugs? I also can't find the idle mixture screw. Could it be hidden? I'd like to use as many parts from the rebuild kit as possible. For whatever reason the new seat from the kit doesn't thread all the way in like the old seat. Yep, starting to regret taking on this repair. New float looks different. Same but different. Not sure if it's okay to use it. UPDATE: I used parts from the kit that I felt comfortable using that included. Needle, bowl gasket, pickup tube o ring, drain plug o ring, seat o ring and float rod that connects the float to the carb body. I really wanted to do a complete rebuild but some parts from the kit just weren't compatible. The aftermarket float looked like it will work but I didn't want to chance it. My advice is to purchase a repair manual if you are serious about doing this rebuild as I'm sure the manual is much more thorough. Parts I didn't or couldn't use from the kit were freeze plugs that I think need pressed in, seat that had different thread pattern, various other plastic parts that I assume are somewhere hidden within the carb.
Great Video's you have helped me out a lot. After changing power pack, coils, plugs, wires, carb kit, fuel pump my 1990 25hp johnson surges/pulsates when at full throttle? Any suggestion on why its doing that. Thanks. D

TOTALLY GUESSING but maybe old fuel line? Had that issue once line was collapsing on the inside causing it to starve for fuel at WOT.
Hey mate, This is such a helpful video and channel. (subbed with notifications). I have a question, my carburettor (same motor as video) has nothing covering the front of it where there are 3 unused bolt holes. Is that right or should there be some sort of breather box? My cousin has an almost identical motor that has a plastic cover/box with a dial on it marked rich or lean.
I wish you had given us a better look at that 2nd measurement and what exactly you were measuring
I know this thread is old I purchased a 1986 30hp Johnson with manual choke but the bowl on the bottom of the carb has a screw with a nut Im not sure where the bigger hose that comes off the left side of the choke goes any help would be great.
So I rebuilt my carbs on my Evinrude 40hp (1995) cheap enought for kit($12) my problem is the seat. The new one seems to big,and I don't want to force it because of the soft metal...so I reinstalled the old one. When I squeeze the primer bulb, gas comes out of the top of the bottom carb...not seating...
Great videos! I recently purchased a 91 ranger with a 150 mercury black max, the dealer replaced the fuel lines. I was going to put a water separator on an noticed the diameter of the lines are 5/16, Are these too small? Do I need 3/8? Great videos!

Hi William, generally you would have 3/8 hose on a 150HP motor like that.
Seems related, pls help. Every diagram I have found shows a core plug instead of a screen on this carburetor side vent. My carburetor has a screen instead. The rebuild kit I bought has core plugs that would fit this but no screens. In fact no website including Johnson/Evinrude sells these screens. There is a big difference between core plugs and screens. The opposite of the carb has a similar vent with a factory installed screen. Part number 4 on this diagram is what I’m talking about. Why the discrepancy? I have a Eslene 28 spl 1992
Thank you very much!!
I rebuilt the carbs on my Honda BF90A and it turned out that some of the low-speed emulsion tubes were cracked! These cracks can be difficult to see, and sometimes are only apparent when you blow carb cleaner through the tube (the cleaner blows out the side of the tube through the crack). So it's probably best with these old Hondas to replace the emulsion tubes.

That’s nuts, that a company recognized for quality and technology would put a component in a recreational product with such a delicate failure mode. I was a supplier to Honda. Their engineers thought they were Gods. Gods my ass, my engineers found and fixed their screw ups. No charge, it was like we should not let them make mistakes. What a rotten business. Retired many years ago.
I just picked up a tracker boat with a 93 Evinrude 40 hp. I did a cold compression test before doing a lake test & compression on top cylinder was 150 & bottom was 149. Did fine at the lake, but idles a little low & takes a little bit to get warmed up. Do those compression numbers seem too high? I trust my gauge but just seems high to me now that i think about it. Motor appears ot be pretty low hours & not used much over the Years

Nothing like setting off on one job, only to run into three more in order to get the first job done. Oh well, it's the price we pay for the convenience of a compact layout. Stu, have you ever given any thought to a parts cleaner? Not the traditional sink-pump-drum of solvent that is usually found in a business shop, I'm thinking of the 'newfangled' ultrasonic (and heated) parts bath things. I know a fellow who has one, and I've seen a few fellows with YT channels that use them a lot, too. There's no pump in them to circulate, no brushes or hoses, the objective is to submerge the object(s) entirely into the liquid (which the owner chooses and supplies). You can use them hot or cold, and you turn on the ultrasonic dazzler thingy, which makes the liquid really seep into the small orifices and they really do an amazing job of getting baked on grime and crud off of the object(s) without the need to scrub and potentially scrape sensitive surfaces. Google shows me several models available for me (needing 120v 60Hz AC), not sure what would be available for the Aussie market.

Stan, I have an ultrasonic cleaner for cleaning carbs from running go karts. To tell the truth, a couple of days in degreaser ( not carb cleaner) , blow out with air, then brake cleaner, blow out and then carb cleaner just before you reassemble seems to be far more effective if the carb is gummed up. If the carb is as clean as Stu s was I would have only used the carb cleaner unless I suspected the cab had a port blocked. Dont soak a carb in carb cleaner- that grey finish is a corrosion preventative coating and it can be destroyed by a long soak in carb cleaner.

Ron Powell yes you’re correct I know because I’ve done it, after I soaked the carb and rebuilt it and Year on the boat and the oxidation grew like crazy white spots all over the carburetor. So I cleaned it and painted it with a epoxy based paint. But even the inside was damaged the throat is still effected and can’t paint that. So when it’s stored now I spray it with WD40 to help keep the spots down.

Ron, David, and Stu; Yeah, I hadn't given consideration to a saltwater environment and anti-corrosion coatings, being as I don't live near saltwater. I dunno, I just figured that those ultrasonics really seem to be the cat's meow for doing the dirtywork (if you'll pardon the pun). I figured that if one were willing to experiment with different solutions, and be willing to swap out what's left in it from the last job in order to put in a different solution for the next job, it might be worth the effort of finding a place to put it.

I bought a ultrasonic cleaner a couple of years back for exactly this job. It works great. I got a cheap one from the local discount tool supplier for $50 USD. It has a heater in it too. I use Pine-sol for the solvent. It works great. It's mild enough so I don't worry about damaging parts. I even drop the jets in there too. Once they are done I rinse them out with water, blow dry with compressed air then carb cleaner to get the rest of the water out. When I am going back together I like to use some fogging oil as well. It might be overkill but at least I know there won't be any residual water.
This video was tremendously helpful! My 6hp tiller motor would bog down when I gave it any throttle in forward or reverse. I followed this cleaning procedure and it now runs great in forward and reverse! I noticed that every couple of times I put it in neutral, it would rev to max throttle and stay there even though I didn't touch it. It wasn't doing that before and wonder if it is a linkage issue or I somehow introduced a vacuum leak? Thanks again!

It could well be a sticking throttle plate. They aren't always hard linked so you can close the throttle but the spring won't return the throttle plate straight away.
