Much appreciated, Kenth!
I can file the stop later if I think I need more vac advance, but will replace the adjustable with the B22 for now.
Thanks for the mechanical timing info. I will try to check mine, but I know it isn't kicking in at idle.
As to getting the basics first, that's where I am.
Compression was 125 to 130 on all 8, base timing looks steady. I have it at 12 now, will see if it likes a different number better.
As to vacuum, I've seen 18" at idle, but now has dropped as it is ragged again.. I sprayed carb cleaner around the carb, got no response. I blocked the brake and tranny ports, no change. Beyond that, how would I detect a vacuum leak?
Original 11 heads, stock 71 intake, seems unlikely I'm not sealing there, but how would I know?
