..........you write........"I get good spark to cylinders 1 and 2. Weaker spark to 3 and 4. I'll replace two wires on Monday, though it seems improbable that two wires in a new set would be bad".........make certain yer firing order is correct. 1,2,4,3 CCW. Very eazy to miss-wire sparkies 4 & 3. While good N-Engines will actually run on just 2-cylinders, tired engines need at least 3 and preferably 4-sparkies working. Otherwize you will NOT START yer engine and it will behave as you have described.

You write........"2. The carb floods very quickly. "........while flooding carb is most likely caused by yer heavy-handed choking technique, or could be caused by sticking float valve, but it is a very likely candidate for NON-floating float. The float occasionally developes pin-hole leaks in solder seam. SINK yer float in GLASS JAR of HOT WATER and watch for tiny stream of bubbles being forced out.

You write........"3. When the engine was running last week, the air intake would "make a gulping sound." Now I seem to get very poor air draw".......almost sounds like you have a "stuck" intake valve. When an intake valve sticks open, you ain't gonnna gitt much "suck". Suck (vacuum) is needed to gitt the fuel/air mixture into the engine. Iff'n engine don't gitt fuel/air, it ain't gonnna run even iff'n carb is flooding. Does that surprize you?..........respectfully, Dell
