I put in new plugs, one new coil, cleaned carb. It runs on both cylinders but it is rough. Won't stay idling as it coughs and spits continually. Point and plug gap is fine.

Could a bad condenser be the problem of intermittant misfire?

Thanx Ken

Welcome to iboats.

That mild backfire, while spitting back, is usually due to a lean carb caused by a restricted slow speed jet.

Remove your face plate and run the motor. Stick 2 of your fingers into the throat. Does the RPMS increase and coughing stop?
