View Full Version : Kaw FH541v Problems

10-10-2009, 03:17 AM
Having trouble with the engine on my hustler trimstar hydro.engine has 220 hours and has been serviced as needed. The problem I'm having is that once the mower is hot and running for over 20 minutes and the blades are disengaged and then engaged again the engine stalls or at best bogs way dowb and slowly works its way back up.after stalling its then difficult to start back up. I have tried engaging at different rpm's with no success. The engine also has a slight miss at all rpm's when not under load. Plugs foul slightly but have been replaced already. There's also a slight clang when first started cold. I have babied this darn thing more than I should. What's up?
