Help 87 not sure whats happening.

OK here's the deal guys i have a 87 b2200 and i have completely rebuilt the bottom end with new pistons, rings, main and rod bearings wrist pins I installed a new oil pump, water pump, timing belt with kit, rear main seal. I put a brand new head with everything new cam, rockers, lifters, etc.. it have a new fuel pump Weber 32/36 and the cats are gutted accel coil, new ignition control module, ignition switch i mean the list goes on but here's the problem: I've checked all vacuum and it starts up and will stay on but it chugs the f*** out of my gas and it drives until about 2500 rpm then it starts to jerk like if it not getting fuel correctly or something I'm at a lost right now I'm kinda stumped any advice would be greatly appreciated.

Check the carbs float level.

Check for fuel delivery, clogged fuel filter, rust/clogged fuel sock in tank.

I agree here. I'm assuming u have a new filter, if not don't even question it just buy a new one (they're only like 2-10 dollars) and try and find the clear ones so you can see if there's any rusty crap floating around in your fuel.

Cusser I haven't check the tank sock, but I bought a clear filter and its clean fuel no chucks. Inlinesicks I will check the float but I think that the carb is taking in alot of fuel when I looked inside the barrel the fuel is kinda just sitting there like it does know when to cut off.

If the float is set too high it will constantly flood the engine with fuel.

OK I check the float and yes it was set high and on top of that the pump was pumping to almost 4 psi. Its adjusted now, time fix a few more things thanks for the input guys
