I have one of these doing duty as a string trimmer.
I had a Homelite before this one and this has so much more power.
I have ofter thought about converting it.
There are guys out ther who will port these and really bring them to life.
Scott charges $65.00 to do a 25cc Toro the cost should be about the same for this.

I think this engine has lots of promise.
