Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
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.
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.
OK< It has a pulse fuel pump and fuel filter, between tank and carburetor, is fuel being delivered to the carburetor? See link below.
Sounds good, thanks.
I see question is still open.???
