Idle way rich

Is that what the engine wants or where you are limited by what you have on hand?

Depending on camshaft, it may want more than 18 initial. Find the point it kicks back on the starter when hot.
I agree with this although I don't think it has anything to do with the rich idle, also advancing the initial timing will give it way to much total timing, I personally lock out my distributer's and just run it at total timing all the time, have done this for years, even before I had a digital ignition that retards it at idle
