Default Re: Engine dies under load.

I am now leaning AWAY from fuel delivery. Every thing sounds so right. Carb check several times. New pump tested. Not running off tank or lines. New filter.
I would:
1. Get a new condenser. 50% or more are bad right out of the box.
2. Set the points more carefully.
3. Retest motor
No result? Try 4 deg to 12 deg timing, in intervals.

Still no result? Try a coil.

These can all be tested, but the prices are low and it's easy to replace these things.

Be sure all vacuum hoses, fittings, clamps and ports are not leaking. Take off all rubber hoses and check them for cracks and holes in good light. Also there are several gasket in the kit for carb mounting flange. Double check correct gasket and that it is oriented correctly. (slots/holes)

MORE QUESTIONS: Did this start happen when running off the tank and still did it after switching to jerry can? When did this start happening? Out of the blue or after work being done? If there was work done, what was it exactly? Do you understand float level AND float drop measurements? These are BOTH VERY important with your issue.
It is pretty common that a B carb can be warped and will suck air. It takes an expert to "fix" that. After all the above fails, next time you have carb apart, set the sections on a flat surface and make sure there is to wobble and no space between carb surface and flat surface. Glass is a good test surface.
