Thanks for the info guys. Mattax, this is a stock eliminator race engine.

I've done a fair amount of working on this carb and it's functioning "OK" but could use quite a bit of fine tuning. As far as the IFR goes, the engine idles decent, but has wanted to die when put in gear. So I'm pretty sure it's lean. The idle rpm is pretty hign, 1300ish. I wonder if I could simply reduce IAB and have the idle mixture screws a little further out ?
