Please help truck running horrible.

Ok here's the deal. New weber carb, plugs, wires, fuel pump and filter. It ran horrible before the carb swap. Drove it about 70 miles I let out of thr gas got back in it and it will not accellerator. Anything more than idle it acts like its flooding. And I also checked the timing.

Sounds like your air/fuel mix is off I've heard that the weber carbs that are being built now are not tuned for our trucks so u may have to rejet the carb also u have to check your base plates to make sure they are completely flat

It ran fine for about 70 miles then it was like instantly wouldn't accelerate.

it is possible that the float isn't set right, it might be stuck up causing the carb to fill up. Check the sight window if it has one.

Also it is possible that there is some debris that is causing a clog.
