i have a 440 twin polaris motor off a 1972 sled it is mounted in a ez go golf cart thought it would have way more power than what im getting one plug was soaked and black meaning to rich ? and the other was dry and black? this was when i was starting it i discovered so i think it being wet was from trying to start it but they were soot black so do i need to back the needle valve off a little being a twin carb it is harder for me to tune this by ear
