Sure - Dubb Jett and Clarence Lee

Do you know how ABC engines work? You want an ABC (this is ABC we are talking about, not ringed or 4 stroke) engine to reach the same temp so the materials will expand properly. If an ABC engine is run too rich the brass cylinder will be too tight a fit, and prematurely wear the piston out.

Note that I said the RPM or speed must be up - not the work. So you use a smaller prop so that the 400 rpms that you do run it rich (in break-in only) still attains the same top run RPM's of the engine - this is the only way to do it right.

Talk to Dubb - a guy that knows engines (he makes some of the top performing 2 stroke model engines in the world).

How about that?
