[QUOTE="cornishwrecker220, post: 1428753, member: 121224"] your jetting is way too rich for the 220...i have a 35mm carb from a 200 on my 220..my settings are as follows..main jet 152-155 (this is riding at sea level & with the airbox snorkle removed + x3 small uni filters installed in the top of the lid for extra air )..pilot jet is 42..you must use the needle from the 220 & clip in the middle position (id number for the 220 needle is R1173L check you have the 220 not the 200 needle ) air screw between 1.5 turns give or take..i run 40.1 mix..i also run the boysen rad valve on my 220..it works well for me, some like the v force3 block..my 220 pulls really strong with this set up..your jetting along with the reeds you are running seem to be causing the bike to run rich....do the above jetting ( & fit new reeds if $ is tight) along with a ngk br8es plug & go from there.
