I want to check the timing on my engine but before i start i have a few questions i would liked answered.First looking at the timing marks i have one thick line with 2 thin lines to the right and 5 thin lines to the left but no numbers on them.How do i know where 25 btdc and 4 atdc are?
Also when checking the timing at full throttle for the 25 btdc(as stated in clymer)is this safe to do so when running on muffs or in a bin full of water.Or is there another way of checking.
