[SEL] ArrrGGhhh! I'm back after 6 years lurking - re: FMZ

[Edd Payne]

Hi Graham.Going by all the literature I have when F/M went to the R mag they 
changed back to straight teeth.I have and have had many F/M engines and this 
is how it has been with all of them.This info comes from experience and what 
is written in 100 years of F/M and power from the past vol 3.But never say 
never.I have a 6HP tank cooled F/M and it has a flat gov bkt but it is still 
fitted with an AB33 and it is bolted down by the base bolt holes not held 
with the typical clamp across the top.
