Customer Question

My 425 AWS with the mower deck engages right away with a jerk but does start. My problem is that it operates in a lag mode for about 4-5 minutes and the engine bogs down while mowing. After that time it seems as if it wakes up and performs perfectly. Any suggestions? Jerry

Twin cylinder Kawasaki. When engine is cold, it may only be firing on one cylinder. Need to 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 one wire is removed, the opposite cylinder is not firing. If that happens, check for spark and if it has spark, try a new spark plug. .
