Generator stalls after 1 minute

Sadly, I was lazy and did not start the generator for 6 months. It is 8 years old but has only a few running hours on it, basically from running it monthly for a few minutes. I drained the stale fuel, refilled then it started it easliy. I was relieved and thought everything was OK. After about a minute, it stalled, just suddenly shutdown and backfired loudly. It started very easily after a brief delay but repeated the shutdown again with backfire. I removed and cleaned the carb, and jets, with carb. cleaner but it did not appear to be at all dirty. I am reluctant to remove the float for cleaning as the pin it is quite tight. The problem persists. One thing I am not familiar with is the carb. electric solenoid. What is it for? I noticed its supply wires look slightly brownish may running warm. Can I temporarily disconnect the carb solenoid wires and run the generator to see if this is a problem or does the solenoid need to have power to enable fuel flow? I plan to check the oil sensor after reading another posting. Thanks.

Check the oil. It's possible the old fuel may have found its way into the combustion chamber, dropping past the rings, and into the crankcase, diluting the oil there, and increasing the crankcase pressure causing a phenomenon called "hydro-locking." Start there my friends!

I'm KindDa surprised that I have had no response in a week. I had high hopes for FixYa so I tried it. Only correspondance so far is from FixYa asking for money. Oh well, such is life.

My son is wondering if the problem could be caused by a slightly plugged up carburetor, running too lean, so when the choke opens beyond a certain point the mixture is too far off and it stalls. He was also thinking that an incorrect float level might produce symptoms like I have described.

Note: I have noticed a generic "canned" response addressing similar stalling problems. I am curious if these people all paid for a response and then received the same generic response which was already available for free by searching FixYa.

    Hi Your son is right.. After some time gas will start to gel up. as do all liquid fuels. You will have to clean out the carb and the jets in side.Then put fresh gas in.Good luck.

Generator wont start up unless i spray starter fluid into it

This sounds like a dirty carbureator. Just bad enough that it won't start cold.

EM 3500 Will start, then stalls after 30 minutes, starts again and continues to staff after 5 to 10 minutes. Oil is fine.

With regrets, I do not have any personal experience with generator troubleshooting. However, I have been informed by some people that have good experience with them that a generator needs to be run for a couple of hours every month to keep the system in proper order. Should a generator sit idle for ten months, the fuel can actually "shellac" inside the carburetor and lines. This will then travel to areas that will gum up - thus the necessity to drain the tank and carburetor completely.
Here is their advice:
Your service person(s) may not be aware of the time the unit sits idle, and if they are aware - then they are not giving you straight facts (in my opinion). I would suggest contacting Honda customer service directly, and explain this situation to them - they will probably be more then happy to have a technician assist you properly. Contact the 'customer relations' number, and they will direct you from there. Here is the link:

I am sorry I couldn't be of more help.

Kohler 12res installed 06/06, replaced controller in Dec 10, has worked fine since . This past weekend with storm, generator started and has run for 3 days , generator shut down with SCFO code - which...

SCFO is either what is displayed just before it cranks or when it is first powered up. Sounds like the controller may have forgotten what engine its running or is getting a bad run signal from the start switch. In either case a 1 year old controller should not be doing this. I would try having a local dealer doing a firmware update as there were quite a few for this controller and if this doesn't fix the problem I would start talking warranty with whoever replaced the controller.

I have an em3500 honda generator which starts stalling out after 1/2 hour to an hour like it is running out of gas and then shuts off. I can restart it and it will run for 1/2 hour to hour and do the same...

Recheck for spark when it stalls. If you have lost spark I would say a heat damaged coil.

You should also drain and inspect the carb bowl. You may have low fuel flow which limits full throttle operation to 30 minutes or less. When it dies you are just refilling the bowl for the next run.

Good luck and be careful!

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.
