Results within 1/2 degree. Put the balancer on and it was also within 1/2 degree.

The hard stop (metal strap across the cylinder bore with a bolt in the center as a stop) method is more accurate than using dial indicator, this is because at or near TDC the crank can rotate a few degrees with the piston not moving much due to dwell.

Try it with a hard stop and see if things change.

Thanks, I was thinking that might be the case too because of dwell, which was why I didn't actually mark my measurements when the piston was 100% up but rather equal amounts on both sides of TDC. This gave me 2 readings on the degree wheel which I used to find true TDC. Now I am wondering if that's the correct way?
If that was correct then I'll just caulk up the balancer to machining or whatever and mark my new TDC on it.
