Can't get timing dialed back to tdc

I seem to remember that it is possible to adjust the bottom bolt, if you are good with working with tools by feel.

I was suggesting that you check that the TDC is when piston is at top. There are piston stops to check that. Google that.

Yes,I did that. When the timing mark is at tdc on the balancer the rotor on the distributor is at the number one position.
