I've been trying to figure out this problem for a while now. The car will start run rough sputter and die or if I give a lot of throttle it will sputter at 1k rpm then rev to the moon or die. As for as I can tell spica is timed right, #4 tdc turned counterclockwise to I mark, and the 2 marks on the spica line up as well. Could this be distributer timing problems? I'm very tired of fighting to keep this car running I'm tempted to put the car up for sale as is if I can't figure this out.
