Talking Re: k jet 450 Vac Advance/Retard diagram non-smog

Bryce , I think you will get a better result with 10/11% static advance using 98 octane fuel. Though the total mechanical advance is the important number. somewhere in the low thirties and up to 35 % if the engine is relatively carbon free in all the combustion chambers. Sometimes one cylinder has a build up of carbon and it will cause pinging.
