What fuel oil ratio did you use right after it was rebuilt? I am in the process of rebuilding one.

@91yotapick - I used a 25:1 ratio, ran it with that mixture for 6 hours, varied engine RPM's the entire time. Have to readjust carbs to run rich with that mixture. Went back to 50:1 and changed the carbs to run a bit leaner.
