Not Ranked
Definitely TDC No. 1 Compression, and not Overlap?
Is this a new engine installation?
Backfire out carb is timing way wrong, or firing order incorrect.
I watch the rockers rocking on the opposing cylinder in the firing order (360 degrees), then bring the balancer around to 15 BTDC, then static time from there.
Usually within a degree or two on fireup.
