Default No power

Starts fine and idles fine but stumbles and no power under load replaced the condenser, no change. What’s next, coil, distributor? Seeking informed advice.

Does pulling out the choke help any at all?

Lawson, I’m guessing that you have been experiencing a heat wave. Mechanical fuel pumps become less efficient in hot weather, having difficulty keeping up with the demands of the engine. Then too, debris may interfere with the pump’s check valves, or clog the carbuetor’s main jets. Yet another cause, also common, is the flex hose collapsing internally. Bottom line, fuel delivery can’t keep up, your engine stumbles.

First thing I'd do is check to see how far spark will jump with a plug wire disconnected and held near the head with the engine idling. Ought to be blue in color and jump at least 3/8" or there's a problem with coil,power to the coil,or distributor. What vehicle and coil/distributor is this,Lawson?...maybe I should know but my rememberer is broken.
All this is assuming the carb is receiving fuel from the pump of course.

The heat wave we have been having affects the coil, particularly if it hasn't been rebuilt to use modern insulation instead of the original waxed paper. Heat causes resistance to rise reducing current flow. Time for a Skip's rebuild.

I have a Skips coil. I now believe it’s probably the accelerator pump. Carb on its way to CharlieNY. Keeping my fingers crossed.
