LX178 with 17hp kawasaki liquid cooled dying when warmed up or when blades are engage

riko73 · Aug 11, 2014

I pulled the radiator,totally flushed radiator and block. pulled and tested thermostat,works fine. Filled with fresh 50/50 coolant. Also new plugs, fresh fuel with system cleaner,cleaned carb. Battery is wore out but hooked up to a charger. She runs GREAT at full throttle for 10-12 minutes and dies. Wait 5 minutes and starts right up. Also when engine is up to temp,I engage the electric PTO,engine dies after 3-5 minutes. PLEASE HELP!!!! If anybody has any suggestions,I would GREATLY appreciate it. My e-mail is riktiff@yahoo.com if you prefer that route.

New battery didn't help. Thinking its fuel feed. Put in new fuel pump, tested fuel flow sensor, works fine. I am able to run at half throttle now with blades engaged. If I throttle to high engine wants to die, I throttle down then back to half and she keeps running. Please help,, I have no hair left because I pulled it all out working on this thing!!!! Lol
