I purchased a Propane Generator from Central Maine Diesel a few years ago.

20 HP Honda engine, Italian generator head.
Paid about $2300 plus shipping via Paradise Freight which was a few hundred.
I see the price is just a bit higher now... But the one I want most is Yuchai which i saw from a website.

Recently it blew a capacitor. Central Maine sent me 2 for the price of one even though it is out of warranty. $39 total for two.

I looked at generators on island but a similar Honda at Quality electric was close to $6000 and it wasn't even a 13750kw. More like 8 or 9000kw if I remember right.....

They have many generators at great prices but this is the one I settled for.

However, it is said that the Cummins generator is more popular than others.

SOURCE: Hard starting when cold, runs rough at idle and any steady speed.

Your carburetors need to be cleaned. The pilot jets are at least partially plugged.

If you are comfortable doing this yourself, you need to remove the seats, fuel tank, and air induction system before you will be able to get the carbs out. Be carefull when removing the fuel tank, there is a wire harness that will need to be un plugged from it to remove it. The wire harness plug runs under the plastic tray under the seat. There are 3 plastic rivits that will need to be removed to get to the plug. The carbs come out as a pair, and can be tough to get back in the boots.

You need to remove the float bowls, remove the jets, and blow carb cleaner and compressed air through them all. The pilot jets are most likely the only culprit, but you might as well clean everything if your going to all the trouble. You should also blow carb cleaner and compressed air through all of the other passages while your at it. Make sure that you can see through the jets and there is no debris left in them. Make sure to clean the floats, needle valves, and float bowls as well.

Then re-assemble

This happens when the bike sits for long periods. The fuel we get now days has a very short shelf life before it goes bad. Fuel oxydizes over time, and it happens even faster in a small amount that is vented which is exactly as it is when its in the carburetors of a motorcycle. When fuel oxydizes and evaporates, it leaves a gummy mess behind. The pilot jets are the smallest passages that sit in the fuel, so they naturally plug first.

You can prevent this by keeping fuel stabilizer in your fuel when ever the bike will be sitting for long periods of time. Myself personally, when I store one for the winter, I like to leave the carbs empty.

SOURCE: Honda 2000i generator runs but cuts out after a short while...

Hate to state the obvious, but is the gas cap vent set to on while you are running it? Also, next time it starts to run poorly, loosen the cas cap. If it runs fine, replace the cap.

SOURCE: yamaha wr 400 2000 model pulled apart carby to clean

big spring is for the dighram! the only other wouls be for the pointy mixture screw
Cheers Rob
wind the screw in till it just stops [not hard]
then wind out about 1 & 3/4 turns that should be a close air fuel mix then adjust idle & mix till you get it right
Cheers Rob

Spark plugs fouling

black soot is overfueling. And as it is a trail bike operating in dirt and mud conditions I would be looking at changing the air filter first. Change to a hotter plugs may help (select plugs up in the heat range ). Check reason for extra fuel ( choke flapping on or float level )

Powermate generator 3250 runs for hours then chokes out runs rough

If it runs for hours under the same a mount of load then, chokes down, make sure fuel lines are fully clear, it may operate with a full tank of gas then when the weight of the fuel in the tank gets less has a problem. When it chokes out fill the gas back up and see if it works again. Also make sure the choke butterfly is not closing again whilst hot. I don't know how many hours are on it, but a decarb may be in order, especially if it runs for hours no issues

Coleman Powermate 6250 only runs with choke closed/air restricted

A call to Elliott Small Engine solved my problem - Oil Guard. I had checked the oil and it was just a little low but seemed well within the normal range. I was told to add more, bringing it just over the Full mark. It seems that the low oil protection system is very sensitive and shuts down the engine even when the oil is withing 1/8" of the mark. I added about 2-3 oz of oil and no more problems
