Default Re: 1929 double a won't start, help

The rotor goes counter clockwise, In my picture the brass tab right hand edge is inline withe the #1 and the points close.
In the other picture the brass tabs left hand edge is inline with the #1 and the points are opening.

So as the rotor turns counter clockwise and the spark lever is fully up, the points are closing when the rotor comes in front of the #1 pin and after its travels the lenght of the brass tab it opens just as the brass tab leaves the #1 pin.

Basically points close when inline with the brass rotor and opens just as the rotation causes the brass tab to leave the pin. If I move the timing anymore clockwise the points would close on air before it makes contact with pin #1.

Theres a bit of play in my cam but not that mutch. I kept it tight clockwise since that's how the rotor gets pushed around. Just like I've seen people set the timing on videos with that nu hex key, "2 rotations clockwise to take out the slack".
