Hey All,
Im running a Z121S with about 145 hours and four years old. All pms and services up to date.
I can mow with no problems for about 30 minutes and then the unit starts to get sluggish and slows down. I disengage the pto and the unit returns to normal.
Today, filled fuel tank half way with fresh non ethanol fuel. I blasted the carb with cleaner before I hit the grass. Fuel filter is new. It still only runs for 30 minutes. I let it cool down and then i do the dance again with it. I have to vote for a fuel issue, carb? What bugs me is why will it run for 30 minutes and then go sluggish? Is there something in the carb that will fail after it heats up?
Any thoughts would be appreciated. Plus, my carb experience is very limited, best way to troubleshoot?
Be Safe! Steve
