"Can somebody tell me what degree to set the timing on a 1991 120hp force with prestolite magneto ingnition? I don't know wheter to set it on 28, 30, or 32 degrees."

"Larry, if you are still looking for the answer your max timing will be 30 at cranking speed or 32 with the motor running..."

Mine has the three lines instead of degrees. I have no idea which line to put it on. Might just take it to the shop. Keeps backfiring when I try to start it.
