I reset the timing on the D1 3.5 v8 last night using a nice shiny new stroboscopic timing light (inductive type) to about 4-6 deg BTDC (Everywhere i have checked says the 9.35:1 comp engine should be timed at 0 deg ) to allow for the gas.
whilst doing this i noticed that the vac advance unit is loose, so i tried to tighten the small cr*ppy torx screws that hold it, but no luck. The one is easy to get to, but the back one is tight on access, as the top hose etc is in the way. It doesn't move around that i can tell, and i don't think it's affecting the timing, but what is the best way to make sure it's secure?
I did think about a blob of epoxy resin to hold it for now, and then remove the dizzy and sort it at a future date, before resetting the timing (again).
Any suggestions from the v8 guru's most gratefully welcomed......
