I have an os vzb v spec .21. I cant get it tuned. I went 2 1/2 in from flush on the hsn. 1 1/2 on the lsn, and the metering is flush. It it sound like its bogging, then take off, with lots of smoke. I have leaned both 1/4 turn, the bogging gets worse, then i richen it, it cuts off. I run byrons 30%. I have never had a motor this difficult to tune. I checked leaks in the tank, tubing etc., maybe trash in the carb? Thanks in advance.

Do what Hambone said. If all checks out go to box stock settings put a new plug (P3) in and check to make sure your clutch is in good working order.
