while New electrical parts are always suspect today....

Debris or water in the fuel will do it too.

A touchy needle in the carb will give those exact symptoms.

I have one Farmall with a very touchy walbro carb on it.

Needle sticks open just a bit sometimes, and I hear the change in engine sound first, then missing and smoking if I don't get after it.

needle sticking shut....quits or pulling the carb bowl drain and getting nothing or a trickle

needle/float hanging open....turn the gas off...if the engine smooths out for a few seconds just before it stalls...bowl was overfull.
