NT running rich but acts lean by balking when gunning throttle at lower rpm under load. anyone had this issue with the NT on the 4 stroke? Jetted down to a 63 and still get a puff of black smoke when blipping the throttle No balk unless under load.
 
If it's bogging, then it definitely is running rich, try putting the needle clip on the top notch.

Hi gary55, Hi Chainlube, I know im a lttle late to the party here...lol.

Probably good advice,

I have an NT with a 5 notch needle on my 2 cycle Zeda 80...I have it at the very top notch because of my 4500 ft altitude and it runs perfectly with a nice cormel brown plug burn...the altitude in Prescott AZ is at a Higher Elevation then me in Alamogordo NM, your at 5,367 ft....DAMIEN
