Fuel Vaporization Using Eddy Carb -- In-Line Fuel Pump Question

A while back someone gave me what I thought was good advice on curing my fuel vaporization issue with my 318 build and Eddie 600 carb, but I searched and could not find it. Or perhaps I recalled it incorrectly. So I have been wearing out my starter motor every single time I turn off my engine hot, and it sits long enough to vaporize the fuel out of that crappy carb. I then crank it for about 5 seconds, which is embarrassing. My options and successes thus far are:

1. Composite spacer under carb. Did that, does almost nothing.
2. New carb. This is my 2nd choice, based on price. But how certain will I be that I will cure the problem.
3. Electric fuel pump system to replace mechanical. Last choice. Very expensive.
4. In-line fuel pump to system to supplement mechanical. 1st choice, based on price.

All suggestions and tips and specifics are appreciated, especially if they are backed by experience that you can elaborate a bit on.
