depending on elevation i have pretty much the same set up as your and im running a 168 main and a 55 pilot. and mine runs great, maybe a little on the rich side i could probably go down to a 165 main and it would be ok. i would suggest starting at a 170 main and go down depending on the color of the plug. hope this helps-Ryan
