I just read the directions again and I can see howthey could confuse someone or at least raise the question. Once you have set your crank at TDC and have a pointer and degree wheel installed and they are lined up on 0 deg., it says to rotate the crankshaft clockwise until the pointer is lined up on 28-30 deg. BTDC and stop, this is the direction to turn the crank the shortest amount to achieve the desired angle setting. It then goes on to instruct you to turn a timing ring with sensor installed counter clockwise until you see it spark. The RcXelinstructions are meant to be used toretro fittheir ignition on an engine other than one with a sensor mounted to the crankcase. I stand corrected but for their intent, the RcXel instructions arecorrect.
