Have you tried checking the fuel filter and gas cap vent for clogs?

Check your timing. Sounds retarded. Scribe your original mark then go 2 lines forward and see what happens.

Possibly the accelerator pump on the carb needs work. Too much air and too little gas. You might be able to get a rebuild kit to fix it. Also could be a vacuum leak somewhere in the intake. Check the plug wires too. If they're old replace them.

How old is the carb? I'd take the whole thing apart and rebuild it and clean it up... if the carb is 30 years old like the shovel, it can't hurt.

Have you checked to see if the coil is bad?
