I moved this from my 2 stroke center as I didn't know what a gurbee skyhawk gt5 was?! In the process I deleted it some how I had Fakeplay re post it I read his post again and decided to look at the vendors to find out just what that type of engine this was. Well now you know how I feel I had no idea it was a good ol china doll engine. I thought maybe its like a titan or something with a centrifugal clutch but being brain dead that I sometimes can be and Fakeplay being good about re posting his post that I lost.
So here you go
this might help?
