Thanks for the information Shrinker, now I understand your point about the
wider LSA with shorter duration. The port modifications would improve VE,
combine this with shorter duration and the same IVC and you get higher
cylinder pressure for improved fuel vaporization and combustion.
You said something that gives me an indication of why the owner insists on a
rich mixture. If the HP is leaning out on the top end, he may be compensating
with a larger jet as opposed to a smaller high speed air bleed. Remember he
runs a throttle stop most of the time, so most of his decisions are based on
high end charge (trap speed).
You mention a gas bench for determining air fuel mixture. What equipment do
you recommend for this?
