Well this is what I have in the carb.

Atomizer is a DQ266

main jet 172

Needle is a k98 with the clip on the top groove

Idle jet is a 60 and the other one in the bottom of carb is a 50.

The slide is a 50.D7

I was reading Tom Barth’s posting in another thread and he says that a K21 needle and a DQ264 atomizer with a 144 jet is good for a KZ engine? Any thoughts on jetting would be appreciated.

No problem Matt, I am confused myself this problem has been going on for over a year now. And I believe if I am correct that backing off the throttle you are putting the needle back into the atomizer or nozzle there fore reducing the amount of fuel and making it leaner.
