Gaz64, at 1000 rpm it will remain idling, I can lower it to 950 and it will run there for a minute or so but then eventually die. The carb is a pedestrian 750, good idea about the idle feed restriction.

vector1, unknown what the base timing is, I do know total advance without vacuum is around 32-34BTDC

Are you guys saying 10" vacuum at idle with this cam is normal?

Ok, you set the maximum at 32-34 with a timing light, but we don't know the next critical parameter as in timing at idle??

I see no mention of how much at idle you have.

I would hope it has at least 15.
