Kawasaki FB460V John deere
I have a 36" John Deere walk behind, maybe mid 80's with a Kawasaki FB460V.
This engine has always been an SOB to pull start, so I got a used starter on Ebay and installed it. Like a hillbilly I jump my mower from my truck, but that's beside the point (I think)
The starter works great, mower fires up and runs good at full throttle about 10-15 minutes, then turns off like a switch. Plenty of fuel, but no spark. After a days rest it will re-start and do the same thing.
My question is if there is a heat overload switch? If I left the pull starter and shroud off the mower and just left the exposed flywheel would that have anything to do with this problem? Could I have the wrong spark plug? The existing one is a Champion CJ14 the guy at Napa sold me.
Thanks for any advice.
