Another question- what needs to be done to prewent flywheel from returning to its orginal timing? place some copper/brass in the space the was ealier occupied by 1/3 of the key?
Did anyone tried advancing timing on solo 633/637/640?
Or should i just buy some spare keys and try it few times?
Cause widening spark screen holes helps a lot.
