First Time Out!!

If you have a power valve in the front, I'd drop it to 71-75 and see what you get.

Don't get sucked into the total timing deal. Set the timing at idle until it kicks back against the starter when warm and back it off 2*. You'll have to reset the carb idle speed, it's likely going to pick up RPM. See what you get. It will be bunch crisper off idle. Then you'll have to alter the distributor, weld or jb weld advance plate, to get the total number you want. If it's OK now at 40*, then run it there for total. Check plugs for detonation specks. Some lighter springs to get advance in by 2500ish and you should be good.
