ooOOooo, that's a helpful piece of information robert! Thank you. Is that advance in the sprocket or the shaft itself? If it's in the sprocket, I might be able to get away with using a stock sprocket. Talking through this will probably clear it up for me too:
With the crank and cam both pointing TDC, retarding the timing gets me just short of the timing I feel I need. The bottom end is strong, but the end of the top end is still a little weak for the highway.
With the cam retarded by one tooth, the top end is nice and smooth, and reasonably powerful (could be better), but the low end is very weak (for a g10) and revving a little before moving from a complete stop is necessary.
It's still very drivable under both conditions, but in both cases, I have to retard the distributor all the way to get the most desirable setting. This doesn't make sense to me though. When I had the cam sprocket at the stock setting, the most advanced setting of the dizzy resulted in a fast idle, rough vibrating engine on acceleration, and no top end. Now that the cam is advanced 1 tooth (18deg), the lowest setting on the dizzy results in in inability to idle (no bottom end). If I advanced the sprocket, shouldn't the...ohhhh. I knew writing this out would help. If the timing was just getting good by retarding from TDC, I should've retarded the cam sprocket! Ha! I'm pretty sure I retarded the belt. Why though is the top end so much smoother now with this way advanced setting? Even that little hesitation at 2k rpm is almost gone...what a wonder. This seems crazy though... How could advancing my cam by 36 degrees make the difference is if works "just okay" now?
