Re: Tried bike for first time this afternoon: DIDNT WORK
Absolutely don't rule out no spark. But when I was a "total n00b," I also started with 16:1, and mine just barely ran. My old snowblower wouldn't run on it at all. As soon as I switched to 24:1, the snowblower fired right up, and the bike ran like gangbusters.
Start with the simplest thing first.
