I confused myself! :) Position of rotor relative to #1 cap term for advance?

Say I've set up, oh, for example, a 2.8 engine, and am doing the timing. I've confused myself! Is this right:

#1 cyl's at TDC. For advance, the rotor should be "after" (clockwise to) the #1 terminal on the distributor cap, right? The firing order is 1-2-3-4-5-6, so the rotor should be between 1 & 2...?

Thanks! I was sure, but I keep thinking about it, and now I'm not.

Yes, that's right. Just make sure you know which way your rotor turns!

You sure about that firing order?

Easiest way is to set the damper for the amount of advance you want and then simply align the rotor with the #1 distributor terminal.

That way you don't have to remember which was the rotor turns.

Really?? Someone told me that wouldn't work! Great! So say I wanted 10 deg advance. The balancer would point to 10, then I'd line up the rotor and #1 cap terminal? Sweet! I'll do that next time, definately- thanks!
