need help with os 8b carb
I recently got a os 77 df and it came with a os 8b carb. need help with setup, if anyone has the directions or can tell me what controls what i would be greatly happy. i think i have most of the carb figured out but there is a little confusion on the needle and the screw on the throttle side with a + - near it.

RE: need help with os 8b carb
That is your air/fuel mixture(low end) it is a very sensitive adjusting screw, it's actually on a cam screw, just turn the screw back and forth and you will see the pointer point to either the + or - + being the rich setting. start in the center
