How likely is it that my change in initial timing is causing the engine to run-on?
I was getting some detination so I recurved and now am running 15-16 degrees initial. The engine runs fine other than the dieseling. It doesn't do it every time. It drives away cold great and idles at 850 in gear and 650 in park. I checked the primary transition slots on the holley and they looked around .060 give or take. I had no dieseling problem in the winter when I was running a high initial timing, which was around 20-22 degrees but have also changed lot of other things too.
Specs
383 stroker
xe284 cam advanced additional 3 degrees
9.8-10:1 static compression
.04 quench
93 octane (runon is much worse with 89 now but used to be fine)
Thanks!
