Harmonic Balancer question

I went to check my timing and to move it to 3*advanced.
The tab with the 12 8 4 TDC, I tried to aline the mark on the balancer with the 4* mark, but it wont stay running near 12*, but it idles smooth near the 10 0'clock position.. is my harmonic balancer off?

well, if i were to get my #1cyl at TDC, i can make a mark on my harmonic balancer that is lined up with the TDC mark on the tab, and that will still work correct?

That will work, just make sure you locate TDC accurately.

Are you unplugging the ESC? It's the brown/black wire just in front of your heater box.

it should have a plug, and be the only wire connected to that plug. You need to disconnect that wire in order to get accurate timing readings.
