Thanks everyone
It was the air jet. This model requires it to be at 3 turns and it was at 4 ish. The run away problem was in the throttle cable at the handle bar end. A few adustments and alot of hours ( good learning ) and all is well.
Thanks again ( I did try all of your ideas )
On the muffler heat sheild there are some sleaves, washers and I think plastic/rubber rings On my 05' ( which is identical ) those washers were worn a bit and lose. Does it go away when you throttle up a bit ??
A couple of hours to figure out it was the throttle cable.
NEW development, it is running good except if you slightly touch the throttle it dies??
Still HELP
I'm in need of direction. My stock engine in my 05' Griz 660 seems to run away in neutral. If you get it In gear it will also run away ( that's fun ). I have totally taken apart the carb, cleaned and inspected. Still, the same. What next?
Idle mixture screw?
Enriching jet?
Float level?
HELP
