I have a Husqvarna YTH1542XP. I've checked the seat switch and the clutch switch. Both are functioning properly. The seat switch may not be adjusted properly, or i may have to tie it down for it to stay in position; it moves a little. Either way, I just cleaned the carburetor ( Kawasaki 15.2 Hp) and it sounds good, just can't let the clutch go or engage the PTO, or it dies. I need some help guys, please.
