detonation / knock issue on 340
Heres the update. installed the carb - quick fuel slayer 600 vac 2nds - a few minor adjustments were needed out the box ( float levels way too high & mixture screws ) took it out for a test and and instantly had 90% less knocking.
stopped and filled up with 93 - while at the gas station retarded the timing. issue resolved. runs like an animal and no detonation.
I really want to thank everyone for their knowledge, ideas and opinions. seems as it was the carb base crack all along.
