so, if i spray carb cleaner on the carb and the engine starts to stutter as if it's about to shut off, then there's a problem with the fuel somewhere? (it was doing this earlier when i sprayed it) forgive me if this sounds like a stupid question but i'm far from mechanically inclined. i sprayed some starter fluid and i still got nothing. in my research, something said that if you spray the starter fluid and it starts but shuts off in a few seconds then it's a fuel issue. if it does nothing with the starter fluid, then it's a spark or compression issue. does this make sense? if so, where do i go from here if the likelihood of the chain being an issue is slim to none? i' don't have a spark tester
