It is a 1994 clasic 4 cyl.twin carbs. When I start it and have to use the chock three or four times it smokes to beat the ban.Almost like it is getting to much oil. After it worms up it runs great.Is there any way to adjust the oil setting or should I have the carbs cleaned ? ps. It is a two cycle and would like to trade for one of the new 4 strokes.
