Did you replace the hard line from tank to fuel pump??? On my 53 that was the problem, totally plugged with crapola. Also you can disconnect the outlet side of fuel pump and crank, see if you have any pressure/flow. These pumps made today seem to be wimpy and do not last long. Or, try another carb. As mentioned if the thing runs with just a bit of gas dribbled in the carb your electrical is fine. I'd also use an inline 'glass' filter with the white screen. I had an old paper filter self distruct, found a teaspoon of that paper in my carb.

It's easier to get forgiveness than permission!
