No. It will just misfire.
If the coil is producing a spark then the HT lead between them is breaking down.
If you know the coil is good then the Igniter is bad. It is right below the coil.
Have you checked the woodruff key?
Rust on the fly wheel and or coil.
Bad sparkplug or Wire. Or worse, bad coil pack or bad CDI or ignition or kill switch.
To change the coil on a 25 hp Kawasaki motor, first, ensure the engine is off and disconnect the spark plug wire for safety. Remove any necessary covers to access the ignition coil, then detach the old coil by unscrewing it and disconnecting the wiring harness. Install the new coil in the same position, reconnect the wiring, and reassemble any covers you removed. Finally, reconnect the spark plug wire and test the motor to ensure it runs properly.
the coil is bad
More than likely the coil is bad. A spark occurs when the power to the coil turns OFF. Ignition points or the ICM breaks the voltage when it's time to fire a spark. Just having voltage to the coil isn't enough.
put in a new condenser. this can be a couple problems, either the spark isn't jumping the gap it supposed and just sparking due to a bad spark plug gap or the wrong spark plugs for your car or your coil is bad which rarely happens but it can with age
The coil to the spark plug is called an ignition coil on a Yamaha EF600. It is also referred to as the spark coil. These two terms are used for any coil to the spark plug in a vehicle.
I'd also check the coil.
