Hello, W/D here.

Try running the generator with the fuel cap loosened. If it runs without shutting down, look for the pinhole vent in the fuel cap, and clean it. It sounds like you're fuel starved due to a vacuum being created in the tank due to the fuel being pulled out, and not being replaced by the air. Give it a try as this is a common issue.
Some generators do not have a venting cap (most do), and you may need to look for the vent, but there will be one.
Best regards, --W/D--

My honda 2000 whisperer generator runs then shuts off after about 3 minutes. What could possibly be wrong?


Always use ONLY fresh fuel... (page 32 of owners manual) it is very easy to forget about because HONDA is such an awesome machine... but EVEN MORE LIKELY...

HONDA has a very sensitive self protection device

Your oil pressure cut off switch could be responding to the WRONG OIL...
DIRTY OIL...
LOW OIL or WORSE... OVERFILLED Oil.

Check it out in your owners manual. ((below) http://cdn.powerequipment.honda.com/pe/pdf/manuals/31Z07610.pdf

Changed filter, oil, full of gas checked gas flow everything is good , when I start m lawn mower it runs , when I engage my pto and start mowing for about 5 minutes it just quits


if this is got the 27 hp kohler engine, I know exactly whats wrong with it , due to grass and engine oil building up in a short time under cylinder heads , it actually makes a tight ball of grass and stuff there !! this holds the engine heat and ruins the ign module that's just above it there , I put two on in one season ( tractor runs 6-10 hrs day 6 days a week ) I finally gave up I bought a Kawasaki 27 hp twin and installed it , now its run for two seasons and no problems
engaging the pto has nothing to do with it , it would cut off if you just drove it around for 15 minutes

I have a GMC 2300w AVR generator which is pull start. it starts, runs for a min or two then cuts out..have clean fuel filter, air filter, spark plug, what else could it be...it still cuts out without...


Do you maybe have regular gas in it? Both Canadian and US regular gas now have ethanol in them and if the generator has sat for 2 weeks or longer then the gas is bad.Remove the gas tank and look inside. You will probably see an off-color blob floating around in the bottom. That is our wonderful environment friendly ethanol doing what it does best. Drain the tank and refill with premium. Restart the engine and do what you need to keep it running for about 5 minutes. If it has the plunger primer for cold start, use it every time the engine starts to die, 2-3 pumps each time. If not dribble a little gas into the breather to keep it going. After about 5 minutes it should start running on it's own. If not you will likely have to remove the carb and get the rubber seals replaced. Ethanol and rubber don't mix well.

After this keep premium gas in all your small engines. It doesn't separate. If you want to keep using regular gas then there are additives in the after market that will help keep it from separating. Hope this helps.

4000 watt buffalo tools generator: Engine Starts, but after a few minutes it cuts out and stops running. No appliances plugged in, drained gas(it did sit for 6 months), oil is full, Plug is good.


Idle speed jet or passage and/or high speed jet/passage is clogged. Remove the carb and inspect and clean thoroughly, then re-install. Set idle and high spped screws approx 1 turn and tune to run smooth from there.

I have a proforce 2500 watt generator and it cuts out is this caused by low oil? if I change oil how much does it get?


Low oil doesn't usually make engines cut out. Clean the air filter, change the plug and wire. If this doesn't help then I think you're looking at a carb. problem. Probably just clogged jets & ports. It's very common on small engine carbs. It shouldn't take more than 2 quarts of oil. Probably not even one.

New Onan 4000 watt gas RV generator cuts out


The generator engine is jetted for sea level. When you run at 24 hundred feet, it's flooding out. That's what you smell. The carb will need to be jetted for high altitude.
