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?
Some people recommend tightening the collar under the stachion hole to reduce slipping. Does anyone know how this is different than doing it with the flower nut?
