I've finally ordered a Malossi 172 kit with the matching MMW head.
The kit comes with a head gasket (or spacer)… will I need to use it with this combination? As far as I understand, the MMW head squish is matched to the kit and adding a spacer would lower the compression unnecessarily.
Also, do I need to retard the timing more than the standard 16°? Fitting instructions say 14-16°, but I've heard that many leave as is.
BTW, I'll be running with a standard carb and Sito +.
I'm hoping someone has experience with a similar setup.
