Timing Issue
hillbilly timing tape.
Put the timing mark lined up with cover mark at 10 BTDC, then put a mark on your balancer at 5 atdc from timing cover. That new mark is at 15BTDC.
Now you can time the engine with up to 25* BTDC using the cover marks.
You can roll the new mark that is 15btdc to then mark same way to get it so you have marks at 0, 15, and 30* BTDC.
I sometimes take a file and cut a line in the balancer and fill with black paint
