Generator Surging and Stalling Under Load - Running Lean?

I picked up this small All Power generator from Craigslist for $50. It does not run due to bad fuel. Should be an easy fix. Right? But this one fought me the whole way.

I have a PowerCraft GP1KW 1000Watt Rating. It is the same engine and same generator basically. I got my in 2008, after hurricane IKE hit us, and still use it. I have run a window AC unit and a light off of it at 1800watts and it did it all night long. I have been though several extended power outages with it, one lasted a week, I have lent it out to friends with power outages, and I lent it to someone after a tornado destroyed there neighborhood, and they ran it for 2 weeks. I used it all the time as a mobile mechanic when I needed power. It is a little trooper. I had this surging issue with mine once and I just cleaned the jets and stuck a mini brush up and cleaned out the emulsion tube and it worked great again. I also had the bearing go out in the generator head (tractor supply carries an Identical bearing). I recently did a preparing for power outages video on my channel, and it was one of the main stars in the video.

You know James, a year or so ago I found I needed an ultrasonic cleaner for cleaning small parts. In one of your videos I was able to see the name on yours and picked up the same model. I have to say it works great and I also discovered starting with hot water really accelerates the cleaning. I failed to use the same all purpose cleaner you use because I had some of the purple cleaner and quickly discovered it turned aluminum parts a very dark gray. Today I use the same product you use and life is good! Thanks again!

[@watermanone7567]

@@Bigguy_33 /Question, are you diluting the purple power when you use it? thanks

[@BKD70]

I've only used Dawn dishwashing liquid a few times, but it has worked extremely well the times I have used it in my ultrasonic cleaner. Also used hot tap water, as hot as it would run from the tap, and then set my heat to 45°C (about 114°F). I don't know how the Dawn will work on carbs though, I've been using the HF SHDD since I saw James using it and the results he was getting. But, the Dawn got the ball bearings I was cleaning so clean, the ball retainers would flash rust almost instantly if I didn't hit them with some WD40 as soon as they came out of the UC. The Dawn is good stuff. Next carb I clean, I'm going to try Dawn on it and see how it does on the varnish and carb crud.

[@matthewrichmond5179]

Those smaller engines are a pain to tune/adjust. The flow through the carb changes so wildly that it has trouble with sudden loads. Also I have found that the smaller carburetors like to have the airbox on no matter what. I have done testing and watched the intake without the airbox and I have noticed that a large amount of the fuel sometimes is ejected into the airbox as the intake valve closes. I have seen this happen also in 2 stroke engines with smaller carbs. I have not noticed it as much on larger engines. Just the smaller ones, so anytime I am troubleshooting a small sub 150cc engine I will do most of the tuning with the airbox on. Great vid and keep up the great work.

[@refinedsolutions1513]

Great vid. I also agree a lot of manufacturers over state the load capacity of their gensets for marketing. This is fixable tho. Had something similar months back, took apart the engine twice, changed piston and rods on the second attempt, no change. Turned out the threaded rods for the carb mount to the cylinder head had worn out leaving a washed out gap of about 2/3mm. Combined with engine vibration this gap resulted in intake leaks. Because it wasn't holding down the carb gaskets tightly enough. Changed the carb threaded rods and then it could take load without shutting off or stalling. Lastly, had to adjust the governors back to spec, for a complete repair. Seems the issue creates a secondary problem in the governor due to excessive movement of the governor arm. 12year old engine, works almost like brand new now. Hope this helps.

[@blakerhoades6356]

I was cleaning out some junk for my neighbor and I came across a bike lift. She gave it to me and it is really nice for working on generators and small lawnmowers. You don't even have to pick it up because its hydraulic. A generator only takes up 1/3 of the space so you have lots of room for setting tools or cleaning a carb.

[@jcondon1]

That is exactly what I need

[@brainndamage]

I bought a non running generator to fux up. It was almost brand new and had classic faults from sitting, stuck needle, clogged idle jet. Cleaned the carb, adjusted valves, changed oil. The engine runs great, but no power output. The auxiliary winding for the AVR on the stator is open. Take the stator off and look for broken wires, cutting off the rope wrapping. Turns out they used ALUMINUM magnet wire! The silder they used had gone bad and crumbled, disconnecting the splice where 2 aluminum wires were joined. Of course there's no chance of soldering that with regular solder, so I cleaned the wire, put on some flux I had for aluminum brazing, and used a torch to melt the wires together, which worked great. Cleaned off the flux which is very corrosive and that was fixed. But in the process of finding the fault, one of the copper wires that comes from the connector broke off of the aluminum magnet wire. I don't know how I'm gonna fix that, I don't have solder that works for aluminum to copper. Maybe I'll try the brazing flux with regular lead solder and see if it sticks. Or just improvise some sort of mechanical splice or crimp. These cheap generators are junk. The solder fails even if just sitting not running.

[@jcondon1]

I have come across that before. I am not sure why I was surprised, but aluminum is a very poor choice on a generator for many reasons.

[@brainndamage]

@@jcondon1 Theoretically it could work fine, but the practical aspects make it a bad choice. I said "almost brand new", it's around 15 years old, but very well kept, it probably sat for most of that time. The aluminum solder crumbled on its own over this time. If the wire were thicker, it could be joined using screw terminals. Maybe I'll try wagos or wire nuts, those could work.

Hi, James. I thought this was another easy fix. Then it got off the tracks and I hadn't a clue. Good for your perseverance I guess. I did suspect that the carb spring was not adjusted properly. Thanks for sharing! Stay Healthy!

[@duncandogster]

Hi James. The generator was still running lean, although it still performed. It needs a little more main jet. Running them lean will burn them up. You want to run them just a tiny bit rich to lubricate the valves and give it enough to catch up with immediate heavy load from idle. You want to adjust it to where the surge stops and then give it another quarter to half turn, to where it doesn't surge or die when load is applied :)

[@josephdignam123]

I have the same generator with a different brand and it’s rated at 1200watts and that’s about what it will do… I think all power just tossed a number in the air when they rated that one! Great video!

[@compzac]

Certainly seems like it, the fact that the original carb was so lean, then the new carb being also incredibly lean and stalling like that, then the website being a melange of incorrect numbers for component values, and that despite the unit barely pulling 1500 watts it has a 20 amp plug it kinda seems like all power just tossed ideas at the wall then said ok we will make all of them work, except of course for a decently powerful engine.

[@shawnmrfixitlee6478]

Great Job again James .. Those darn china made generators seem to run lean even out of the box to get the run time per tank . If the carb gets even a micron of anything in it then it goes to surging .. The only fix I have found that works is to buy a good set of carb jet drills and go one step at a time .. You did perfect ! ENJOYED..

[@kthwkr]

I am amazed at your temperament. If I had done all that work and got that engine running so smooth and then it just stopped on a dime the instant there was a load - I would have exploded with a string of expletive's deleted.

[@dljones61]

If you had an extra main jet I'd suggest drilling out the main just one size bigger. Seems like you are right on the edge of lean. Anyway great find and thanks for posting

[@Daviecrockett64]

I drilled main jet out to .75 mm, that made a very significant performance improvement all around. Over here in Australia ours run at 50HZ or 3000 rpm so a bit slower than your 3600 rpm. anyhow mine starts and runs 1375 watt 240 volt grinder no worries now, where as before it would just die every time. Thanks for the video

[@P_RO_]

I have a similar issue but lesser. Surges or 'hunts' at standby but not not under load. Clean the carb and it's good for a work day then soon surges again. Might try opening the jets next time I have it apart. Got my money's worth out of it and plenty more already- some of these cheap ones seem to be OK, maybe the older the better?

[@compzac]

True but honestly the generator companies were tastefully lying even before they just started outright lying, take this generator for instance, on the tin it says 2000 watts, now imagine your a first time buyer of a genset, you walk into the harbor freight and you see this genset on the shelf your going to thing wowie i can run my refrigerator, microwave and computer on this thing at the same time during the power failure... but you failed to notice its 2000 surge 1400 continuous, for years all the companies even honda have listed the surge on the tins, which to me seems a little shady as they should list the continuous, if i buy a genset that can handle the loads i want it to as continuous then the surge will definitely be ok. so its kinda they have been lying or tastefully fooling customers for hell at least 20 years.

[@brianperkins6121]

Going to reflect on possible issues. weak compression , poorly adjusted valves,, stuck camshaft compression release (if it has one), camshaft timing off (engines with plastic timing gears will do this when the gear slips in the shaft) or cam timing not correct if it uses a belt driven cam. worn cam not opening valves far enough. restricted exhaust (if it has a spark arrestor for instance) a badly deteriorated fuel line (will quickly gunk up jets) restricted fuel flow through the fuel inlet valve , also check the PVC crankcase vent valve. a bad fuel tank vent allowing for the formation of a vacuum in the tank , fuel filter restricted fuel flow

[@Mikesorrento3344]

I find that sometimes these engines do not run well when air cleaner assembly is off. I find that applying a light oil and saturating foam filter will help engine run a little richer. These jets are often too small due to EPA regs.

I would step up a little larger on the main jet .

[@oldsranch]

Ever thought of checking the air/fuel ratio with a wideband setup? It would be interesting to see the initial lean running ratio and then what it takes for it to pull the load correctly, and also to measure the difference in how much richer they run with the air filter in place. Just a thought! A friend that works on this stuff sarcastically says "The factory finds out where it runs perfectly, then leans it out two turns!"

[@additudeobx]

James, I know you fiddled around with those carbs more than enough times, but after the bought carb failed at 750W, I would have been interested in replacing the primary jet (Not the main, the one you had to vice grip out) in the original carb with the jet from the new bought carb. My thinking is that the original carb might have been spec'd already to the machine and the only problem in the beginning was the over-seated / stuck primary jet.

[@larrysmall3521]

I did not know that you had a variac James. They are a good way of varying a load if you don't have a load bank. They are 98 or 99 per cent efficient. However when used in this way over a short time scale that does not matter at all. I am always impressed by the way you mix and match pieces of carburetor in attempts to make them work. Even then they do not always work but you always try. I reckon thjat you must spend a fair proportion of the money you make from fixing generators and the rest and selling them on new tools and equipment for yout garage/workshop. Keep up the good work.

I doo the same with stuff I repair, I recently bought an auction lot with 5 Miller generator welders all had sat for years but with full tanks of fuel, it was stale but I drained it all out and ran it through my work truck, closed loop efi motors have no problem with mildly stale gas, the short term fuel trims make up the difference. It no good in a carburetor because the fuel mixture is fixed by jets. Generally speaking stale gas burns fine under a slightly richer fuel mixture. Wouldn't recommend doing it with a boosted engine though unless it's direct injected due to the lower octane rating

Great renovation as always James. Odd though that those cheap 2 stroke Chinese 800W (?) generators do give out 800W but they are much happier at 700W. I have seen an idiot on KZbin put a 2000W saw on one and then complain when it cut out.

You can adjust the idle screw for higher idle revs just till it stops stalling under load/surging ,when you use a near max load appliance these cheap carbs aren't very responsive and going from low idle to full throttle under load results in a stall before the motor gets to rev up to match the load. It fixed the issue for me when cleaning the carb etc didn't help surging/stalling under load. you should locktite the idle screw as well as they like to vibrate loose again .

That harmonic surging when is load started is just killing me... I put neodymium magnets under the governor to stop oscillation

Pilot jet to small time to used the micro drill bit. It's fun working on this things.

[@gregorypiercesr.794]

On the jet that u had to remove with the vice grips try brazing a nut on the broken end and you could still use it, good chance it will work. 👍

I wonder if you jetted the original carburetor the same way if it would work. Maybe would run with jet turned in at normal setting then. In some cases turning the idle screw in a little so the governor can't overshoot when it backs off the throttle will prevent surging. This doesn't work if it is starving for gas or it it causes the idle to be too high.

Curious how it would have reacted with the airbox as the little bit of restriction creates a stronger single at the jets.

I found it!!! Harbor Freight!!!

Looks like one of Harber Fright Generator

and ive seen the hole for the small spring on the carb plate..drill another hole just bit further on the plate for more tension.
