Hi Harley, this pic was taken just after I made my second mark, which was the BTDC mark. Normally that’s the first stop mark a person would make, but I did the BTDC mark after the ATDC mark. Yes, the piston was resting against the stop as it was 7deg away from—and on its way to—TDC. The ATDC stop falls exactly 7deg on the other side of my balancer timing mark.
