Do NOT spray carb cleaner into it. It needs oil as well. Make a premix of fuel and oil and use that.

So if it fires while spraying fuel into the carbs, you may have a fuel problem and not a spark problem. Does the bulb stay hard after priming it? You can start there. If it does not, could be the fuel pump. Try pumping the bulb while starting it.

Air Assualt!!!

If the bulb stays soft, do you get the smell of gas at the carbs? I'd replace the bulb and lines with it first. If that doesn't work, rebuild the fuel pump.

Sounds like the carb is maladjusted? What do you mean it jumps to high? Is this when you give it throttle or not?

My guess is it's dropping a cylinder and then the cylinder is kicking back in. You'll have to trouble shoot that from the plugs, wires, coils, on back to the switchbox. I've got a '74 also and have had both coils and switchbox give me this. It depends on if the miss follows the coil (when you swap them) or not.
