Ok rebuilt carbs pop off at 18-20 psi, replaced all fuel lines, cleaned all filters and selector switch, compression is 140, I have spark, and fuel comes out of front carb fuel pump and out of carb to rear carb but does not come out of rear carb to the return line. It will fire for a second on a squirt of brake cleaner then die. What am I missing? Why won't this run?

Try removing your spark plugs and pour a shot of fuel in each cylinder, replace plugs quickly and fire. This should start for a couple seconds hopefully that will pull the fuel thru by the engine runnin. Repeat if necessary.
