John Deere 425 hard start
Another JD 425 hard start issue.
Kawasaki FD620D V twin gas engine, 1460 hours, 1999 model serial numbber 71992.
Recently became hard to start, crank and crank, sputter and back fire. Initially suspected fuel pump and replaced - no change.
Engine is flooding, plugs are wet and won't fire.
Dealer suggested ignition control module, no change
Took carb off, cleaned, new float valve and fuel shut off module (tested bad), no change
Checked to see that choke closes completely - OK
Crank with no air cleaner and raw fuel is pulsing out of carb venturi - instant flood. Carb looks so simple (?)
Spark seems strong, checked with extra plug, both sides seem OK. If can start runs good and will start OK when warm, but not after sitting a while.
I am out of patience and ideas. Any suggestions before dragging to dealer?
Thanks for the help.
