Thanks for the feedback guys. So i have 139 tooth flywheel (4 teeth per inch... whereas the 168 is 5 teeth per inch.... based on Deve's Inline-6 Engine book.
Still curious though, unless my research is wrong, all 261 engines were 12v based and SHOULD have had 168 teeth.... strange that mine has the 6v based 139 teeth.
Anyway, I'm back in business. Time to show it off at some Christmas events ;=)
