RHS head 416 at the track...part 'tree

What did you find that you thought was making it rich? Please explain.

Each time it was started it left a PILE of soot under the turndowns. Black smoke the first part of the burnout, black some duing the hit and early in the run, black plugs...

But see, that's what happens when it idles on the main jet rather then the idle circuit. What I didn't realize was two things:

1) Without drilling holes in the primary throtle blades, they were open far enough to expose the transition slot.

2) With our carb tweaking the signal is so much stronger it was pulling alot of fuel past the boosters at idle.

Just basic Holley stuff...along with me being a dumbass like I said.

We had made other mods to the carb THINKING it wouldn't need the primary plates drilled, and I was so stuck on that I couldn't see the forrest for the trees.
