AMC 304 Carb Replacement - Suggestions?

I have a 304 that I just rebuilt, and now the carb is acting up - so much so that I can't get it to run. I had a friend rebuild the carb, and I guess he didn't do it correctly - the float bowl is not filling up at all. The only time it's getting gas is when I'm pushing the accelerator. I'm considering just buying a replacement carb because I don't want to fool with another rebuild kit, and I honesty do not know what I'm doing.

I was thinking of either going to Summit Racing or Jegs. Currently I have an AMC 304 engine, and a Motorcraft 2100 or 2150 carb. I wanted to know if you had any suggestions on a good carb for this engine. I want to go with a 2bbl with an electric choke. Thanks in advance for any help/tips, as I am new to the world of carburetors!

The 2100 you have is what I rec. If the bowl is not filling up either then the float isn't operating correctly or the fuel pump is FUBAR. Start there.

I'm thinking it's the float - I had a friend rebuild the carb awhile back. When I press the accelerator, gas sprays into the carb. I removed the fuel line going into the carb and it was sending fuel, but the gas was not collecting properly in the carb itself. When I removed the fuel line, hardly any fuel came out of the carb. I am hoping and thinking the fuel pump is okay--right? I may have a source for a free Ford 2bbl carb..hopefully that will solve that problem.

If fuel is spraying out the fuel line when removed and turning over the engine the pump is ok. Next I'd remove the top of the carb and see how much fuel is in there. You can have someone briefly turn the engine over and see if fuel sprays into the bowl. Be careful as you may have fuel spraying everywhere.. pull the coil wire first.

It really sounds like your "friend" eff'd up the rebuild. If you do now want to mess with it, call Pony Carbs in Las Cruces NM and have them rebuild it and calibrate it. They may just do an exchange. I had a 2100 on my 304 and it was great. It is probly the best carb to install on a 304 for offroad IMO..
