i recently got my hands on a 1988 318 with a front loader. it does not run that well and puffs white/grey smoke when you hit the throttle. it came with a brand new carb. a niki 146-0626 it says on the side. is this the correct one? or at lease one that should work? thanks for the help guys. love this beast btw. will love it more when it runs right
oh PS. this carb has no mixture screw. the hole is sealed with a silver dot and some resin over it.
