[QUOTE="jonboylaw, post: 473911, member: 17621"] Definitely something a little iffy with #1. I would try a set of Bosch plugs as a first step. I have heard others having problems with non-Bosch plugs for some reason. Also, are you able to swap the dizzy with someone to eliminate that? You may have a sticky base plate. On the timing, max static advance is around 30 BTDC, on overrun the vacuum will pull this higher, so make sure your advance measurements are on WOT. What you should see is the dizzy advance jumping noticeably once you come off closed throttle as the vacuum comes on and gives it the advance it needs. I run a Megajolt and have around 40 degrees on high vacuum overrun conditions. Do 1&2 share the same Venturi and fuelling in the carb? If so then they should be getting the same mixture which does suggest electrics to me. Sent from my GX64 SatCom phone using Tapatalk [/QUOTE]
