I recently ran across the website for Chuck Ney
Enterpreses (http://www.chuckneyent.com/) and read
where he advocates straight bore cylinders instead of tapered, or choked,
cylinders. I'm assuming the engine manufacturers have good reasons for
designing taper into their cylinders (variable temperature expansion
characteristics over the length of the cylinder?) Mr. Ney, on the other hand,
claims a vast amount of experience indicating better performance and longevity
by boring the cylinders straight. I know we have some very knowledgeable
engine people on the LML so I'd like to get their take on straight vs
choke.
