Did the engine ever run with the present carb and electric fuel pump you now are using before your low end engine build was done 

Russ is good with electric pumps in our year cars so tell him which pump you have especially if it was just installed in the car 

Stay Safe

If the mechanic said the carb gets clogged with gas, then that tells me it is flooding out. You either have too much fuel pressure or the floats are set wrong.  What electric fuel pump did you put on?

Sounds like the points and timing are out of adjustment
When was the engine tuned up last time ? 
What was the car doing for you to bring it to a shop for repair ?

Enjoy
