New to me car. New distributor put in. Car was running terrible before (distributor obviously not only problem!) Here's the problem: for the life of me I can't get the timing even close. It is either about 25 deg BTDC or 25 deg ATDC. I have pulled the distributor MANY times and rotated it one spline either way, and it doesn't seem to solve the problem. My dwell is right at 40. I read that each spline is 30 degrees, so theoretically I am missing one in the middle, but I swear I had that thing off 5 or 6 times today, marking the position of the rotor each time. What am I doing wrong?
