To answer your specific question wich I see no one else did. Yes it matters what your #1 is designated. #1 has to be at #1 #1 on the cap is at the notch. If you have it there and still runs poorly then you are of a couple of teeth when you set the distributor. Probly have the timing retarded a little pick up your dist. and move it cunterclockwise looking at the motor. If that dont do it move it clockwise a couple of teeth.
