Have you brought it to TDC to make sure your rotor is pointing towards 3!?You may have dropped the dizzy in,off by a couple teeth.Will give you odd settings.Good luck.

i taught it should be pointing at 1? the dizzy is sloted it only goes in two ways, how could i be a couple off? wouldnt it be right or 180 off?
