WoW THANX geezer ~ worked on the truck @ the military DIY auto shop (Five O Motors) and the mechanics there helped me a lot ~ tested the distributor vacuum advance IT IS NO GOOD the actuator diaphram is NO GOOD ~ adjusted the initial timing to 8°BTDC ~ they think I should adjust the idle air/fuel mixture screw & they said the tamper plugs are hardened metal use a dremel grinder to make a slot ~ Finally the Made in China laser tach broke after one use

ALOHA GUYS
