I have a yth24k48 it some times loads up on start up but the biggest problem is going down hill it will load up and smoke nearly die have to stop the blade and it will after a while clear up when I cut the thottle back . It also does it on slight hills to the left.
It is a float problem.
Also they have cut the size of the air filter down in height. Not good
I hope they get it fixed only have 30 hours on mine.
I received notice that the U S Consumer Products Saftey Commission is starting an investagation into this problem. Notify them of your problem. It needs to be fixed. Ilove the trimmer except it has burned my arm.
WHAT WAS THE FIX? IHAVE THE SAME PROBLEM.
