I don't know about "eliminating the chance of" . When you go to the automatic timing gismo, you still have to do the dance of where is the timing at idle and high speed with no regard for load on acceleration and climbing a hill. The first thing I would check if I were there is; the starting point at idle, Very Slow and not much power. After that, you have about 30-32 deg. to work with which is about 1/2 way down on the lever, maybe 2/3.
