Rick,

I thought the lower the number the richer the mixture?

"AFR
The Air fuel ratio is the most common reference term used for mixtures in internal combustion engines. It is the ratio between the mass of air and the mass of fuel in the fuel-air mix at any given moment.

For pure octane the stoichiometric mixture is approximately 14.7:1 or λ of 1.00 exactly.

In Naturally Aspirated engines powered by octane, maximum power is frequently reached at AFRs ranging from 12.5 - 13.3:1 or λ of 0.85 - 0.90."



Also the silver springs that I am using are the heavy springs not the light springs.

Furthermore, the noise is only heard under aload.


Boy I am really confused now!!!!
