Ok, I have a purple spring and no ball in the secondaries.

The small screw to adjust the vacuum secondaries is on the bottom, o off came the carb. The play or gap is in spec.

I adjusted all the valves, they were all a bit tight. like 1/2 turn too tight. i used comp cams suggestions, as it is a comp cam. I took the wiggle out and then did 1/2 turn. They are a bit noisier but, I gained 1" of vacuum.

Idle timing at 20* car responds well, however all in around 3k im at 50*

I found a leak in the trans, the guy who rebuilt apparently didn't tighten the front pressure port plug after testing, so it is leaking. have to wait for the exhaust to cool down before i remove, seal and reinstall.

I pulled the electric fan off, ordered a flew fan spacer, will install as soon as it arrives. luck Hope this helps cool the motor. I would think at 220* i would start to see some pinging or detonation on pump gas in a 10 to 1 motor. shruggy Maybe not?
