Ongoing problem since Mar/2010. Model 5501/NG, GH-410 engine.
Some times unit will start fine on maintenance routine. Other times it will try to start or start and run like the choke never released. (Like a lawnmower with the choke on) In fact my service tech knows that the choke isn't releasing but can't figure out why. He has worked on this several times focusing on the actual choke assembly. Does anyone know if this could be a problem with the control board since it sends a voltage to operate/release the choke?

Any assistance would be greatly appreciated.

To be filed in the "For What It's Worth Department".

My 8KW with the GH-410 had a problem starting. Sometimes it would turn over at what seemed like one-half speed and then start; sometimes it wouldn't start the first crank cycle but would start on the second or third attempt; sometimes it would start up just fine. Anyway, it finally gave up the ghost and wouldn't turn over at all. The service man came out and replaced the starting motor and that fixed everything. I know that this may not sound like your problem, but if your engine is turning over slowly (assuming the battery and connections are OK), it might be the starting motor.

Maybe you're having a problem/issue in addition to the choke.

Thanks for the info but mine always cranks over ok but sometimes starts and won't go to normal speed. It might do that two or three times and then start normally and sometimes it will start normally. This past Sat it started but ran for the full 12 min with choke closed. Very frustrating problem.

It sounds like the choke plate is sticking shut. You can remove the air box to gain entry to the choke assembly. Manualy close the the ckoke to see if it stays closed and does not release. if it stays stuck, remove the screws holding the solenoid, insert a thin flat washer between the spring and solenoid. This will keep the choke plate from binding on the plastic. This will keep the choke plate from closing to where it will bind. Have not seen a problem where it gets below zero, and units running on propane.
