When I put the Holley 2bbl. on my truck, I had to mess the the carb mixture and float for a long time before I got it adjusted right and it ran good. But it's too bad I wasted the money on the 2bbl, now that I want a 350 which i will probably have to buy a 4bbl for.

Oh well, you learn by making mistakes.
Glad the 350 runs good for you. Congrats on getting it in.
