I got my new carb, a VM18, and reeds last week and i decided to bolt everything onto my NC50 (with a recently bored intake, stock exhaust) today. I've tried every jet I have (70, 75, 80, 85, 90, 95, 100) and no matter which one I have in the silly thing fourstrokes like mad. What jets do you guys run on your carbs to get the stupid thing to run right? What can I do to make it run right?
