JD 445 Kawasaki FI engine surging
The last time I was cutting grass the engine started to run erratically. It would rev up then idle down, like quick surges. It was similar to when you start it cold, and give it gas too quick, only slower, more like it was running out of gas.
I had run the gas out that was in there all winter, and filled up with five fresh gallons before I started cutting.
I bought a maintenance kit, and put on the new air filter and spark plugs. It still does the same thing.
I'll try a new fuel filter next, when I figure how to remove the old one. Any ideas???
