[SEL] Flywheel dangers

[John Culp]

Well, from my own viewpoint, (1) there's not much hope of greatly 
improving the efficiency of an IHC M, the compression ratio being the 
principle determinant of efficiency and the M's design and mode of 
operation not lending itself well to a great increase in compression, 
and (2) it's a collectible antique. I like to keep those original and 
not modify them in ways that aren't easily reversible. The engines and 
the major parts like carburetors and magnetos aren't made anymore, and 
modifications of them are going to "mess them up" in the eyes of future 
collectors.

I'd recommend trying to work on the efficiency of something like a 
modern Briggs & Stratton or Tecumseh go-kart engine. They're typical of 
small engines widely used in modern farm and garden equipment. You'll 
find a lot of information and helpful resources from the folks who race 
them. :-)
