How do you figure?
To me, it seems to be running on #5 only, lol.

My guess it that the throttle blades are too far closed.

I guess i have to figure out what is wrong with the other seven. Still cant get my head around it.
I always square the primary throttle blades and adjust...if needed....the secondarys.
