Valve Job

[wingfsmith]

I have a 2006 Hustler Z with a 23 HP Kawasaki with 675 hrs. The mower has been trouble free and works great on country terrain. I the last few months I've notices a "pop" when accelerating to full throttle after idling. After talking with local Hustler mechanics they assure me that it's quite normal to require a valve job on that engine at about 500-600 hrs. Anyone else ever heard this?

Before going through a complete valve job, start by checking and adjusting the valve clearances. Yes, a complete valve job with those hours may be needed, but trying adjusting instead of a teardown first is much cheaper.
