I am still struggling with my 70 Mustang base, 302, 2V, Motorcraft 2100D. Engine tries really hard to start but just won't get going. After trying to crank ventri are wet with fuel, plugs are wet with fuel. This is without pressing accelerator while trying to start. Covered/eliminated thus far.... New plugs, points, condenser, rotor button, rotor cap, coil. Carb rebuilt, in fact just bought another kit and replaced power valve and accelerator pump just to be sure. Float is set to spec. Idle screws are at 1.5 turns out, choke is at index. Timing is right. I'm stumped! Help! Thanks!
