Spent most of this arvo screwing up the cam timing on my 115 think i started it by putting the wrong reference mark outside on the prop driver and case.Since then it's been hours of whistling and joy.I can get the inlet valve at 2 thou rotate the crank 360 and at a guess have an easy 50 thou gap,bit of a bother
You have to rotate 720 degrees to get a repeat
But to get that much difference, you were not in the correct spot to begin with?
Why not set the intake when the exhaust is fully open and the exhaust when the intake is fully open?
