Default RE: Another Brillelli Masterpiece - Briggs 34cc Four Stroke

Your 20" props seem a bit large even if it is the 40cc. Is it possible it's lugging a bit and/or overheating. I think you would want to prop it so that it gets 6500+rpm. Somewhere I read that it's not a good idea to mess with the jets or needles.
