Stumbles on start up? Primer Solenoid? Spark plug gap??

I changed the gap from .040 to .030 and it ran kind of rough. I put it back to .040 and it ran ok. I guess my problem was I was priming all kinds of wrong lol

I use Champion plugs -- maybe you are running something different. Go with what works for you.

Might make sure the jets on the carbs are clear -- may be able to do that without complete disassembly.
