I set the timing initially by pulling out the spark plug in cylinder #1 and spinning the crank shaft pulley by hand while a buddy made sure it was the compression cycle. Once we knew it was on the compression cycle we took the cylinder up to TDC using a long screwdriver in the plug hole to feel when it got to TDC. 1st cylinder TDC matched the mark on the vibration damper on the crankshaft. Once I got it to TDC I pulled the distributor cap to see where the rotor was aimed and adjusted the distributor so that the plug 1 location on the cap matched up with the rotor location.
Can't set the timing with the light because I can't get the RPM to back down to the range to match up with the manufacturer specs for setting timing.
Did a bunch of reading on connecting distributor advance to ported vs manifold vac. Have tried both and it runs better on manifold vac.
What are the few other things you think it could be?
