Can anyone tell me, what is correct ignition timing for my CPC 18075L
(Century Plus clutch drive) engine?
I mean in crankshaft degrees or piston millimeters BTDS.
Problem is, that there are TWO holes locating the magneto baseplate to crankcase, and I`m not sure which is the original one.

Ignition timing on a CPC
All the ones I've ever measured seem to average 23 degrees before top dead centre. 5 degrees either side seams to make virtually no difference.
