I have a 250 trailblazer that is doing the EXACT same thing, I didnt tear it down or anything, it just started doing it one day. But it runs good with the choke on fully. How do you adjust the fuel mixure?

 

Hey Fishslab - how do you like that Roller Clutch - is it noticeable?

Also, the engine compression and seals are no problem. Just prior ro overhauling it, it ran strong. Even now, it easily pulls wheelies but then I hit that dead spot...

 

I think the roller action secondary is worth every penny. It especially is a kick in the **** on the 2 stroke. It is extremely noticable and give the 2 stoke some what of engine breaking because it reacts so fast. Did you come up with an answer on the dead spot?
