Why, yes, the email address is mine, and gives detailed info, with pictures of how to add stops to vacuum advances that have the correct vacuum level for the engine build application, but too many degrees of timing for that engine, A simple stop that separates vacuum level from degrees given, so vacuum advances can be used as they should be, on full manifold vacuum, to supplement low to no load operation.
Stop the pin travel to limit advance, DON'T PUSH THE PIN INTO THE SPRING.
A vacuum advance should never be used as a second acceleration curve on any non EGR valve engine. ONLY time ported vacuum should be used is on functional EGR EMISSIONS engines.
