You need to first check fuel pressure and compare that to spec.

Because your engine is modified, I won't know what those specs are, but generally, it should be around 7psi. Also, if equipped, check that the fuel pressure regulator isn't leaking (Including the vacuum line leading to it).

Next, check the float level of the carb. It should be centered and not allowing to much fuel into the float bowl.

Finally, check the idle mixture screws. You'll need to hook up a tach.
