I just realized another good thing about inline fuel shutoff valves??? When running the mower for the last cut in the cutting season, shut off the fuel valve and let the mower carb run out of gas. Then push the mower in the garage for the winter months...Done! Next, I'll install a dash fuel shutoff valve on my Sears 5hp Snow blower, Wherever I can install an inline fuel shutoff an any ground equipment I'm doing it. But, one Spring it took me an hour to find why my tractor wouldn't start. I forgot I install a fuel shutoff valve. Ha-ha-ha! But hey, I'm a 73 yo. These videos from Bruce taught me a lot since retiring, and Bruce puts quality in his work guys. I like that!

Then, it stopped running and hasn't ran since.

Thanks for helping me understand better the relationship between the air vane and the carb. By the way, using the magnet to "grab" those 3 nuts holding the gas tank is a nice tip. In the 21 years that I've owned my Deere walk behind with Briggs engine, I must have removed that gas tank 10 times and usually drop a screw or 2 when fishing them out of their recessed housing. Also, I never thought to use the discharge chute to peek under the unit while changing the oil. Thanks for that also. Anytime I handle the oil dipstick tube assembly I thoroughly clean any dirt and gunk that is present in the area around the tube insert. Should that tube pull out entirely (easy to do) the debris is sure to fall into the oil sump. Best to you.

Great Video again ( Encore' ) Non'c Bruce........... 3 things I want to mention to you and your viewers ............ 1st... Yes the ratchets you use are the best for us small engine guys.... The Craftsman and Snap On type round heads are the fine click type used by Aviation technicians and other types of Techs for tight fitting and small areas where a few clicks makes a difference......... 2nd... That gasket on the air box you used is more pricey than the other gasket that comes in the 498260 carb kit from Briggs...... The gasket with no primer bulb hole and the holes for the air box tabs goes on the mower you worked on.......... That way you can save the pricey one for a minor repair........ I don't remember the part number right off the bat....... 3rd... The spark plugs on the 6.75 and a few other models are supposed to be gapped at 25 thousand instead of 30........ Plus Tard Mon Ami ~!~!

Bruce it sure looks good. So I would say it was that choke arm. Because she started on first pull. I too have a 2012 self propelled she runs great until this year. I was cleaning her up and a ting spring went missing the vane spring. Will I found it but it took me hours to figure out how to connect. All done now. I need to get a float pin mine seem to have taken off last year so I put a small paper clip in its place. It seams to be not working this year. Gas pouring out of filter area. I will take apart soon and hopefully I can buy a pin locally. I sure don’t want to use a mail order place. Thanks for all your help.

another fine job by the lounge singer lawn mower mechanic....lol

I have the Troy Bilt version of this mower that a neighbor tossed out. It would not fire at all with either gas or starting fluid. I disassembled the carburetor and found gray sludge in fuel bowl and center port of 1/2” nut plugged. From what I could tell all passages were clear. Tested with known good plug, tested coil, checked gap, still no joy. I lost track of how many times I dis & re assembled that mower, wondering what I was missing. I checked the kill wire at the mechanism and then pulled the bail. The brakes were releasing but it didn’t move far enough to break the ground connection. I bent that tab up just a bit and the mower started first pull. Still runs a bit rough but now I have a spare /loaner mower!

Do you have a drain plug in the bottom of your mower? My lawnmower is 3 years old and no drain plug on the bottom of my mower it's all sealed in on the bottom as of a Briggs & Stratton. I have to use a suction hand pump to pump the dirty oil out of the base by where you fill it up. My mower will not run as of the choke plate will not open and I have to stick a screwdriver in to hold the round choke plate open to get it to run. So an idle spring must be broken or some other connection. After watching your video I will check my mower out as of what you have done.

Thx, I’m gonna have to go over it again. I also have a theory the auto choke is malfunctioning. It opens way to fast. When I manually push it back a bit, it runs perfect! But if the auto choke was malfunctioning, wouldn’t it not open at all?

Bruce one more question the handle that we pull down to start and let go to stop does not work on mine. Sometimes I don’t even have to pull down to start. And to stop engine I have to carefully remove spark plug wire.

The stop cable that moves the lever by the engine must be sticky. Remove that and see if it can be loosened. Go careful and if you take your time it may be able to be lubricated.

Bruce. I swapped out two different carbs on a 6.75 briggs and stratton mower yet it still has a miss to it & the plug is white at the tip. What hat to look for? Nice mower just not running smoothly.

A white tip means it is getting too much air. So---a seal near the carb, loose carb, manifold seal. You can spray carb cleaner on the joints. If it changes RPM that is your weak spot. Just note carb spray is flammable.

Also along the lines of an air leak, sometimes the plastic air filter cover can warp especially when over tightened like this mower. I have seen double gaskets between the carb and air box to remedy the leak there.

Thanks Raymond. I just did that on an older one. ( I used a used one and a new one haha) Although it is the carb that mixes the fuel and these are upstream of the carb.
