Initial timing set @ 30*. Engine seems happy?

Corrupt_Reverend said
Isn't the harmonic balancer keyed to ensure proper index? The balancer on the engine has the timing marks stamped in it @ 2* intervals. I'll double check anyway, but I didn't think it could go on wrong.

I don't have a vacuum gauge. Could I use my timing light to advance until the RPM is the highest, then retard a little? Or do I need a vac gauge To find it proper?

Thanks for all the help so far! :)

You are correct in that it is keyed for proper index, but that is provided you have the correct balancer and it has not moved like RRR said. You need to find TDC on #1 and verify your timing marks line up.
