Sooo.... I pulled the plugs
Plug number four had damn near no gap whatsoever. May have been damaged when I pulled the head off, can't say for certain.
Just put new 7's in at .030 gap, and it does definitely seem better, ALMOST. She's more responsive, and if I hold the idle around 3K, I see around 14's~15's on the wideband.
Let it just idle and it goes off the scale again, but smells uber rich. I'm definitely beginning to think that the plug wires are crap. I'm going to get OEM tomorrow and replace them, then see where I stand. I don't think it's a fuel related issue due to the fact that when I hold the revs high, it leans out and is really consistent.
Oh yeah, and before I forget:
I just did a compression test on the motor. I'm seeing 120-120-120-120 so we're good there. 8.5:1CR motor with 272's installed.
