Is there an electrical solenoid on the bottom of your carburetor ( thank you government regulations) If gas was drained before winter lay-up the float woud be down at the bottom letting fuel in there are often crankcase pulse fuel pumps that could have spring loaded ckeck valves stuck in them I asked early on if there was a solenoid looking coil on the bottom of the carburetor it's normally closed with a needle valve seated without power to prevent fuel flow there are a few places to look best of luck to ya gary
I have a similar wont start problem and if the fuel solenoid is off without power in the normal state, I would like to manually
override the solenoid so that it will always be on and disconnect it. I always us a manual fuel off valve at the end of
each session to run the fuel out of the carb. . So does anyone have instructions.... I guess I should remove the float bowl
and look inside to see how the solenoid works and try to figure it out. Has anyone done this ? Any downsides to this approach ?
