Thanks for all the tech-tips. I agree - I'll discon the carb; see if she flows when she cranks. If she flows, I'll attempt to ascertain the amount of flow vs crank time... Otherwise I'll see if the floats may need adjustment.

A typical fuel pump (for carbureted) is only about 4-6 psi... not a lot. If I get flow, then it's likely the carb. But I also have to keep in mind that there may be simple residual pressure in the lines.

Thanks Otto - nice to know this isn't unheard of. I admit it's been a long time since I've had to replace a fuel pump.
