[whisker frisker]

Won't stay running at idle. Cuts out and back fires thru carb sometimes and stalls. Runs great with speed?

 

[utakts]

Classic symptoms of a lean idle circuit. Probably a dirty or partially clogged carb. Try pulling and cleaning the low-speed jets. Ethanol fuel doesn’t help either.

Clean the carburetors.
