FUMES 73 Plymouth Valiant

I took it to a mechanic shop for a tune up and it started every since 2 yrs ago. Went back again and they replaced the carburetor and the problem still exists and became even harder to start. So, went to another shop and they added I think an electric fuel.pump. I'm not good with parts.

Without a lot more information, we’re all just going to be guessing.

I mean, is this a slant 6 we’re talking about? Or a stroked 440? Is it a factory gas tank or a 10 gallon fuel cell?
