A friendly consultation your spark plugs come out black very dirty or do they go well?, is that to rule out a fuel excess, if you have a fuel excess you can have three situations, one that the low throat does not close, that the needle is stuck or that the float is very high, now you have to check your pique pump can do that failure too. But I think it is a carburetor with the bad condenso, not the car, ha and cool Hojo the distributor and the rotor lid itself, see that the Fiat 147 had that corduroy the car was warmed and the rotor does not work the rotor nobody knows because they only did it hahaha luck.
