He suggested with the mods I have and with my elevation that I go with a 160 main jet, leave the stock pilot jet, raise the needle one clip, and turn the air/fuel mixture screw all the way in and then back out 2.5 turns I did this before this post and it was running way to lean the plug was brite white so this Is why I am asking other pred owners to see If they have any suggestions....................................... And I will eventualy send him my carb....................I am just trying to get It close enough for right now so I do not burn up my engine....................
