Monojet carb problems

[pseigmund]

Hi All,

I am having some problems with my Rochester monojet on a stock 292 in a 1970 3/4 ton with a 4-speed tranny. The problem is that I pull the choke(manual choke) shut and it starts fine but after it starts to warm up, it will die if I don't keep the choke almost closed. I can pump the gas to keep it going if I do open the choke but then I get some backfiring. It will also stall when I try to put it in gear and take off. It seems that it is starved for gas. I have a new fuel pump and checked all the lines. I get good gas coming out of the line near the carb when I crank the engine. I just double checked the float level and needle valve. There must be some other problem with the carb that is making me have to keep the choke closed. I put a carb kit in it a few weeks ago so it has a new accelerator pump, etc.

Any ideas?

Thanks, Pete
