Please help me set my timing, dwell and advance

[Walter_Middie]

I recommend checking the timing at high RPM before doing this, but you can get more adjustment out of your distributor by simply removing it, and turning the rotor so that when you re-install the distributor the drive gear is moved by one gear tooth.

It's safest to have the engine at TDC with the rotor pointing to plug wire #1 before removing the distributor. Not necessary, but if you lose the orientation of the distributor while it is out, it is easier to get back in if the engine is lined up as I described.

I will put it at TDC and see where the rotor is pointing and mark it before removal.

Thank you for your patience,
Austin

A couple of things to help understand the timing:

The crankshaft pulley turns clockwise - so in your picture you show it firing after it has gone past top dead center (ATDC). You want it to fire somewhere to the right of the marks before it rotates to top dead center (BTDC)

The rotor also turns clockwise - so to advance your timing, you rotate the distributor so that the contacts in the distributor cap reach the rotor sooner, which is counterclockwise.

When you rotate the distributor counterclockwise, you should see the timing marks moving to the right - or moving clockwise around the crankshaft pulley. This is advancing.

Approximately 1mm of distance around the crankshaft pulley is about 1 degree of timing.
