My bro-in-law (sister's husband) has a John Deere 165 with the 460cc Kawa 12.5hp engine.  Helped him with it some, cleaning his carb, and saw his spark was weak.  He got a new coil, and she fired up fine cold, which was his main problem, as it would gas foul the plug from the weak spark.  His other problem was once hot, if you shut her down or killed it, it would not restart.  Just turning over with a "flurp" sound as if firing fuel with a stuck open valve.  He ran into some fence wire while mowing today & killed the engine, and again, nothing but the flurp sound.    After it cooled, it fired right up & ran fine.  Looks like he'll be bringing it up to me for a good look at it.  Thought I'd ask you guys what you know about these Kawa engines, as all I know about Kawasaki are motorcycle & ATV engines.  Any quirks in these engines?

You don't think it could be the valve clearances do you? Would make sense unless you guys already checked them.

That was going to be my first thing to check if he brings it up here.

Daniel, I don't know anything about this particular motor, but the Kawasaki motor on my golf cart has been bullet proof.

Hope it turns out to be an easy fix.

I have seen two different types of problems with a Kawasaki like that.

 

1. Time delay module.  I don't think the Kawasaki FB460V had that, but if it does there you go.  $20 bucks and you join Willie "on the road again."

 

2. Igniter.  The price hurts on this, but I would venture a bet (if there isn't a time delay) that you could be seeing it going toast.  They don't suddenly die, they can play like a condenser and flicker until they completely knock off.  I think they are $100 or up.
