Honda Powermate Generator - No Compression?

[@Niesha266]

I used to use an Epson ET-2550 kzbin.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.

[@watermanone7567]

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

[@jcondon1]

Thanks. Did not think about cutting it or heating to remove the limiter. I did check the valves at one point. Did not make the video, but they were dead on. Thanks for the advise.

[@gregorypeterschmidt620]

Waterman one (or James), please consider producing a video on the valve adjustment and jet drill out....I'm very interested and I'll bet others are too. Thanks!

[@daverose8772]

Use a #78 micro drill bit on the low speed jet.

[@dontblameme6328]

Likely just drilling or going up on the main jet is all it needed.

[@capohd28]

After seeing this, glad see the one I have same as this is still rock steady on it’s original carb after many years. Mind you I’m at 1400+ feet elevation which might just like a lead sea level jet. I always run the gas out in carb when I’m done using it. I’m sure that helps.

[@ron827]

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.

[@gregorypeterschmidt620]

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....

[@stevejette2329]

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

[@Chris-yy7qc]

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.

[@jcondon1]

That makes sense.

[@CitroTeam]

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.

[@ReignOterror]

James, take a look at the valve lash. Incorrect valve clearance can severely affect intake vacuum and make the carb run lean.

[@PeterLawton]

Excellent point. On the one hand, I like knowing that drilling the jets can solve the problem. But on the other hand, I have to think the generator ran fine when new, with the original jet size. I've just never known where else to look.

[@PeterLawton]

So how does that work? Is the intake valve open for too little time, sucking too little air and too little fuel?

[@bobadam7021]

The first thing I thought of when it was hard to start. You shouldn't have to drill out a brand new OEM carb. Unless you're trying to make horsepower, but that's not what this channel is about. Also explains the popping out, and even the burned air box.

[@jcondon1]

@@bobadam7021 I almost never drill a jet out. Usually can clean them up and get them to run with OEM jetting. I checked the valve lash off camera and it was dead on. Was just as surprised that the new OEM carb did the same thing. Thought this one would be a simple cleaning after opening up the carb that came on the machine.

[@nicklutz61]

I love your videos. Well though out, methodical troubleshooting, and you admit when you make a mistake. Keep 'em coming!

[@bertgrau3934]

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

Great Job James. Sticking with it and figuring out the issue. Most would have given up when the new carb didn't fix the issue.

[@oldsranch]

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!".

[@adnacraigo6590]

I like the discussion that your channel generates. Plus, I learn a lot about troubleshooting with your patient style.

[@ericvaughn1126]

Wow. Admire your patience and excellent foresight replacing both of the jets in the new carb when the issue persisted. Bummer to have to modify the jets so much though as the typical homeowner is not likely to have the micro drill bits or want to monkey with doing the work. I get annoyed at how long it takes to drill out jets when I need to do it, but maybe my cheap set needs to be upgraded. Top quality as always and please do keep them coming! Early mowing season has started here in NC so I hope to move some mowers, blowers, whips and pressure washers that are taking up space while getting equipment in for service too.

[@claycox6818]

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.

[@wildefox1478]

Some people like me put a electric heater close to engine to make easy start but some are stupid and set it way to close

[@Totally_Unsupervised]

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.

[@jcondon1]

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.

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.

[@davidschipsi1316]

It freaks me out to drill jets. The generator I’ve been working on I must have gone up five drill sizes one at a time till I ran right. Now it runs perfect. All else being good I will not hesitate to increase the size of the jets starting with the pilot jet. If it surges under load I’ll go for the main jet. I’m putting those number drill sets to use.

[@davidschipsi1316]

This generator had a knock off replacement carb and it was way off. Number one problem with gen is carb fouling. After cleaning runs lean. Aftermarket carbs can be off. Even new gens seen to run on the edge of running too lean. Maybe with a little wear, carbon buildup, fuel type, very small air leaks and altitude tend to make matters worse. Oh for the days of carb adjustment screws.

No chance of cutting the brass and won’t hurt the reamer if it’s not jammed up to the point in the reamer taper.

You should set the valve clearance and clean/gap or replace the spark plug before chasing carb issues. You could be tuning the carb to compensate for other issues, especially if the PO's friend had his fingers under the valve cover.

I agree. Did not show it, but changed the spark plug and checked the clearance. Clearance was dead on. Felt like changing the jetting on this was not the real fix,. Like you said, compensating for something else.

[@dondondon5695]

Another issue is that as time goes on, the gasoline sold in North America has more and more alcohol in it, resulting in less power available in the same amount of gas. I've found that on older snowmobiles, the jetting that worked 20 years ago is too lean under the same conditions now.

[@Delekham]

I have to ask this question. Why did the Voltage go up 2 Volts when adding another 1500 watts? 37:02 We clearly see 117.8-Ish Volts. and at 37:15 we clearly see 119.2-ish Volts. I am only curious..I mean no hate.

[@jcondon1]

Hey this ain’t rocket science. We did learn a lot here discussing this. I have removed the little plastic stop caps on weed eaters and cut a screw driver slot on occasions. Glad it runs well now!

my powermate 7000 has been used only once . it has been sitting with fuel for a number of years. i tried starting it but it would not start. i believe that there may be gum in the carb. will pull down the carb and clean it up. will let you know. thanks for the video

How did it go?

[@akawireguy1197]

Troubleshooting. Both rewarding and frustrating.

Thanks, James...this was an interesting one!

James you should really do a cylinder leak down test before dealing with anything in the carburetor. I've gotten into a habit of doing that first before digging into any machine that comes in my shop. It will immediately tell you if you have bigger problems before tackling the smaller ones. Recently just had a snowblower come in where it would idle fine and soon as you put it to full speed no load it would start to backfire stumble and want to die. Turns out it was a combination of leaking valves intake to be specific and the guy stripping out the spark plug threads where compression was leaking from the spark plug itself. After doing a thorough valve job on both valves and reaming out the old spark plug threads and putting in a thread insert, all is right again. Had I not done the leak down test I would have done the same as you and tried cleaning out the carburetor thinking that it was a mixture issue.

Thanks, will do a leak down test to be sure. Would expect the engine to be down on power though. It kept its speed better then most under load so may have dismissed that possibility too fast. I feel like drilling a jet out is a bandaid and not really a fix. This one caught me off guard. After seeing the inside of the carb, thought a simple clean would have fixed it.

Jim, FYI, If you treat you rubber/neoprene hoses and parts/grommets with AT 205, it will recondition brittle rubber, to like-new Resilience. I have brought back many crank case breather tubes that woul have snapped otherwise.....it cost from 8 -12 dollars on ebay.....

Fuel stabilizer. Stabilizes fuel so much it turns into super stabile jelly.

[@andyrichardson6188]

More info, please. I thought the carb issue I had was because of too little stabilizer which resulted in some varnish. Could it be the stabilizer is causing the problem? I could try to turn over my fuel more often, but I go out of my way to get E0 gas for my small engines. Getting it more often will be a hassle, but possible.

[@Chris-yy7qc]

​@@andyrichardson6188 The most important thing is to empty the bowl of the carb when before the generator is put into storage. Then I strongly recommend to use ethanol free gas on small / carburetted engines or engines which are not used very often. Fuel stabilizer helps, but after a long time the fuel with stabilizer tends to turn the fuel into jelly. So in my opionion for short term storage stabilizer relly helps, but for long time storage it makes it worse (imho). How I do it: Empty the bowl of the carb and change the oil before putting the gen into storage. On gens with a fuel tank made from metal: I fill it up to the brim with fresh, ethanol free gas to protect the bare metal inside from rusting. If the gens fuel tank is made out of plastic I drain the fuel completely, because the fuel can actually partially dissolve the plastic. I dont use any stabilizer. After about 1 year of storage I drain the fuel (put it into my car or bike) and replace it with fresh fuel. That way I never had any fuel related problem with my gens.
