i wanted to say thanks for your work with the timing on the HT, and i was wondering if you happen to know the exhaust duration in degrees for the 66cc. thank you
sorry i didnt reply,i decided to order a spare engine (66cc)
so i can take my time with the 48.
i was more curious about the alignment in the crank (twist)
but i will be looking at balancing once i get the case repaired.
