Oh... I think I just got it... do you mean if it is not a TDC it will ast like the cylinder is running and force it self to TDC once air is induced?

If it's not *exactly* at TDC when you introduce compressed air, the force will turn the crank, pushing the piston toward BDC.
If there's a TDC mark in your balancer, that should be for piston #1 (and presumably #4), assuming that the mark is accurate. You'll know pretty quickly if it's not, so stay out of the way.
