Re: HEI distributor tuning problem
As Lee H mentioned if it was a used HEI.
The last used one I got the grease was so dried out it was preventing the mechanical weights from springing back. They would move but sort of stiff. Check carefully for vacuum leaks and with a "dial back" timing light check regular and total timing. If you don't have one, rent one or borrow one. It's easier to see total timing with one of those. As far as using higher octane, it's more expensive but one tankful would let you know if that's your problem. .
