Help with getting MC-9 to run
#5
Thanks everyone who responded both here and through email.

I tried a couple things:

1. Swapped out the carb for an HL232 off my West Bend. Engine ran great. I wanted to prove to myself that it is a carb not an engine problem.

2. Soaked the gaskets in fuel/oil mix overnight and cleaned the carb thoroughly with carb cleaner. I did notice that the diaphragm in the carb (I think that is what is called, the one that hits the fulcrum that opens the fuel inlet valve) is a little stiff (would soaking it longer help?). Engine ran a little better (more time between choking) but still would not run well without choking.

Based on this I'm sure it is a carb issue. I don't have an extra diaphragm to try and haven't been able to find any online. Does anyone have a source they can point me to for that?

Thanks again,

Michael
