Re: Pretty little 49cc engine!
Mains are the same size, I built one of my engines the first of the year. Maniac did you notice how close the cases are to the crank? No need to stuff or anywhere to put anything for that matter. The crank in both of my 48cc engines fit the same way, neither cylinder has those size port tho.
Your results may not be the same,Greg
