I used to use an Epson ET-2550 kzread.infoUgkxciSwynMJ7PnUvvx11rewiu-yFBkZTl53 , an early model of the ink tank style. It worked well, but had one nuisance that drove me up the wall; if you didn't put it in high quality print mode you'd get a streak across the page. I'm happy to say I have yet to see this with this printer. The print quality has been fantastic so far, the set up was super easy. All in all I'm very happy with this printer.

Ah, I think we have a fisherman working as a carb doctor. The wire bristle is a great carb cleaning tool but I prefer the wire in a bread wrapper twisty because it is easier to hang on to and not loose. The melted airbox could be from the frequent use of starting fluid or a substitute such as acetone. When purchasing a small engine piece of equipment, I always inspect the starter rope. A worn rope tells me it has been started many times or it is hard starting. The shut down "pop" can be eliminated by holding the throttle butterfly in the idle position for a minute or so to let the engine cool down and then shut the ignition off with the throttle in the closed position. When shutting off an air cooled engine via the ignition, the governor opens the throttle butterfly wide open and the carb meters a large amount of fuel into a hot engine. This unburned fuel passes into the hot exhaust manifold where it is ignited and creates an explosion. It can be very damaging to the manifold gasket. The carb solenoid is intended to prevent this. The metering needle which appears to be unremovable can be if the tab is carefully reduced in size or the surrounding area enlarged. An engine needing to be slightly choked appears to be running lean and turning this needle open by 1/4 turn should make a big improvement. I have resurrected many engines with this procedure. This is the best internal combustion engine channel on MeTube with quality content, no obnoxious music, no foul language, great delivery and lots of good tips. If all generator owners knew what Dr. James knows, generator sales would plummet.

Ron, I was thinking acetone also. The plastic looked 'chemical melty' not heat/flame damaged in my opinion. Especially since the carb side didn't look bad....

James: I do hundreds of Honda's for the Amish and others. First make sure the valves are adjusted to about 4 to 6 thousands of and inch. They are famous for going out of adjustment. Second, you can remove the plastic stop on the adjustment screw by heating it with a hot air dryer or shop heat gun, it will get soft and should come right off. I have also cut of the little stop tab with a small cut off wheel on a Drummel tool. I also drill idle jets on lots of them. The EPA sets them far to lean and causes many issues. Different altitudes makes it necessary to drill the pilot jets. Also thought your governer spring looked a little loose. Sometimes they get stretched out by people trying to replace carbs and it will also help cause surging. Great video and those are excellent machines when cared for properly. Thanks P.S. check out Dony Boy's latest video on the tiny screen under some of the newer carb inlet fittings. They plug really easy. Thanks

Really glad you didn't give up in this one. Surging seems to be such a common issue so I'm glad you solved it!

Thanks for showing the projects that drive you crazy. Otherwise new people think it's all straightforward and simple.

17:00 I think they used lots of starting fluid to get the engine running. The fluid collected at the bottom of the airbox and ignited somehow. Maybe it backfired a little bit after it was in storage for a long time (sometimes the valves initially dont close all the way after that until the engine ran a couple minutes). Thats why the airfilter is in good condition. It wasnt there.

I been trying to watch them all

The Honda power equipment (and many others recently) i've worked on has been intentionally been very lean to meet a Calif emission standard, and the damn engine has to be really hot before it runs right on the lean mixtures they are requiring. On some stuff, I xref a replacement carb from a prior or older model where the main jet is adjustable. The factory adjustment seems to be "Find out where it runs perfectly, then lean it out two turns!".

JOB WELL DONE- With modifications, SUPER!!

I love your videos. You are so patient and methodical in everything you do. I don't work on many generators however after watching so many of your videos I do believe I could do a decent job at it. I do work on walk behind/push mowers more. This video reminds me of one particular mower that I was given, repaired and then sold, however I do wish I could get that mower back now. It was surging just like this engine. Initially it was surging worse, however I drilled out the pilot jet and the surging was less, but didn't go away. I made a slight adjustment to the governor and increased the rpm a bit and the surging went away and the mower ran and cut great, but at what I believed it was a bit high on the rpm. At the time, I was tempted to increase the size of the pilot jet again rather than making the other adjustments, but was afraid I would destroy the jet. I believe that would have been the better option to try. That is why I watch your videos along with others, in an effort to try to improve myself/skills. Thanks so much for all of the great content you provide. My actual business is in lawn care, and one of my assistants is interested in helping make repairs to our equipment. I have directed him to your videos as well as a couple of others because there is so much to learn from y'all. I do a good job with the equipment we use daily, however when it comes to other brands, there is a skill that I have still strive to acquire.

Jim, one thing I've found that cleans small holes well, is a strand from a piece of wire rope. We have a rather unlimited source at work as this is used on semi truck door seals. Your way seems to work well, and it's unlikely you have the same access to these. We've used this technique on cleaning the overhead bug spray nozzles to great success.

Hello. I discovered this channel just yesterday and I've watched dozens of videos because I like this theme, mechanics. The reason for my comment: after I bought a new battery for my car and the problem was the starter brushes, I dedicated myself to learning mechanics. I never needed to go to the workshop again, neither I nor anyone in the family. Father, father-in-law, brother-in-law, nieces, no one else paid for repairs in workshops. Then I learned carpentry and saved a lot of money on furniture. And part of the family too, which made me some money.

Lots of interesting bits in this and some contradictions. When backfiring on shutdown, first thing I check is a leaking needle valve / float adjustment. I use the inner wire off a twist tie rather than 'abuse' my wire brush. Top marks on another good diagnostic presentation.

I have this exact model. I have taken meticulous care of it and it has given me no problems except I had to lightly clean carb once. Always use ethanol free gas in it, and change out the gas regularly along with the oil.

Shave the tab off that screw and adjust it. They want them running so lean for air pollution but then they run like crap

I notice you never drop or throw down your tools I like that .🔧

.002 was truly a butt kicker in this scenario. Another great job and video.

Thanks for posting this. I have the model 6500 H which is a very similar generator to this one powered by the same engine. I think I bought it in 1999, so it’s it’s an older product. I’ve had the very same problem with engine surging and more recently low power up output. No amount of tinkering was going to fix this for me, and unfortunately the small engine repair shop was unable to do anything except hit me with an invoice for trying. I’ll have to study this video again to see what exactly it was you did to get the engine running smoothly and strongly. It looks like you opened up At least one of the Jets to .020 of an inch. Thanks again.

If helps to have some extra jets in case you go too far. Start conservative. You can always open it up more, but cannot put the material back. If surging under load then focus on the main jet, otherwise the pilot jet.

I worked on a power washer, had a similar carburetor. The guy that brought it to me said, I think it has bad gas. I pulled the spark plug, had spark, I checked for compression, absolutely no compression. Pulled the head, no bad valves, the intake valve guide had moved towards the valve head and was holding the intake valve open. I cleaned it up took it to a machine shop, they heated the head removed the valve guide. They knurled the guide heated the head again drove the guide back in. Did a valve job and now it runs great. I also drained the gas from the tank flushed it, Cleaned the carburetor, and it was gumed up bad. Now it starts on the first pull. I enjoy watching your channel. I was very interested because of the low compression. Thanks for all the information

The back side of your air cleaner grid looks to be fine... That melt is from using of using the wrong starting fluid trying to start this thing. That's a chemical melt, not fire melt.

Not this video but another one has helped me. Twice I have used your tip to remove the spark plug, fill the bottom stroke of the cylinder with rope and be able to loosen the nut on the flywheel to remove it. Mice had nested and chewed the insulation off wires causing a short and cut thru a wire powering a headlight. Neither were generators. The generator video parts are over my head. I would have taken it to the repair shop had I not watched your videos.

Most times I’ve had a surging problem like this it has turned out the be an intake leak or clogged jets. Usually the gasket. One time it was a gas line that had dry rotted from the inside out and basically turned into a flapper valve.

Our same model does the same thing brand new. I tried everything you have, gave up and put a tiny vice grips on the choke holding it slightly out. You can also lay a small cloth or rag over the governor arm to muffle the surging. The fuel cock lever has a spring that ours broke and it leaks and you have to buy a whole new fuelcock.

Is the generator case arcing to the through-bolt? At around 25:00, look at the discharges at the top of the generator;
