I am new to this site & secrched this & found no compatble results. I have a FB 460 Kawasiki on a John deere walk behind that has died. I tore in to it & found that the Intake valve seat was cracked & the guide is loose or moves when the valve opens & closes. which is why I have only 50 PSI. of compresion. I was told that this is not repairable? Any Info that any of you can give me would be Apreciated. If this is not reparable then I will have to decide what to do next get a new or used motor or a new or used mower. Thanks in Advance for the advice.

You were told correctly, It's non-repairable.

Time to start looking for a replacement.

Call this place; http://www.smallenginewarehouse.com/ Have all your engine numbers and it wouldn't hurt to measure your crankshaft also before calling.

Is there any thing that caused this to happen? Or is there something that can be done to stop this from happing? Or is it nature of the beast ? Thanks

Most likely from old age (high hours) possibly being over heated (grass build-up around cooling fins). This is really not a common occurrence, The best thing to do is keep up on maintenance and keep the cooling fins clear of grass debris.
