for what it's worth, I had exactly the same problem. I checked the oil
level and it was fine, but I changed it anyway, I was due. I replaced the oil
with the Honda
high performance synthetic stuff, but still the same problem!
I checked the oil level about a week later, three weeks ago, and though there was oil on the dipstick I was able to dump in at least another quarter-pint or so before it rose to the top of the stick. Immediately afterwards the engine
did the 'start and then stop' thing once or twice, but hasn't done it once since that day.
in short, before tearing apart your generator
, try changing the oil and adding a bit more than you think is necessary - fill it up full, then pour off the excess. Worked for me.
