Twin cylinder Kawasaki engine. Run a cylinder test, Loosen the spark plug wires and with engine idling, remove one wire at a time. Engine should continue to run. If engine dies when either wire is removed, the opposite cylinder is not firing. With this engine check for spark on dead cylinder. If it has spark, check compression and if compression is same as other cylinder, remove the rocker cover and check the valves.

how would it be a cylinder issue if it's starting for a bit then bogging down? It seems more of a gas issue to me
Expert:  Curtis B. replied 1 year ago.

It just is a starting point. And coil may only fail after it warms up. You may need to run test when it is acting up. But is something that should be checked. Cylinder not firing, is the most common cause of low power/ bogging down.

It fires up and runs fine when spraying it with starting fluid until that runs out so I think we can eliminate cylinder problems. It seems to not be getting fuel properly to me

OK< It has a pulse fuel pump and fuel filter, between tank and carburetor, is fuel being delivered to the carburetor? See link below.
