I've got a CVK off my 400 Bayou. I'm having trouble with it loading up at low throttle. When I open it up at full throttle with it in neutral, I'll puff a little black smoke till it gets to the uper RPM. Also sputters getting there.

The thing is I have a total of 3 jets in my carb, I know what the main is and the slow jet. I was wondering what the other one is, is it a piolt jet??

Here is what I have in it now.

Main - 125
Slow jet - 42
Pilot?? - 85

Please help me here, I have a ATV trip at the end of this week and I need to figure this out. What are you guys running??
