GOOD CARB ADJUSTMENT?? Help
Tomorrow i will be takeing the diaphragm out of my new carb with the needle and putting them onto my old carb seeing it ran better with old carb compared to new.
Where would you suggest starting the eclip on the needle off at all the way low, middle, or high? and the a/f screw on the side should i go all the way in and 2 1/2 turns out to start there? or what is your input!!! My current plug is black when i took it out if that helps any! |

Gy6 carbs should start adjustments at 2 1/2 turns out. 99% of the time the final adjustment is somewhere 2 1/4 to 2 3/4.
Set it to 2 1/2, then take it out for ten miles, let it cool completely, and do a plug chop. |
Your plug is black, therefore, your bike was running extremely rich.
Do not adjust deceleration needle until you have determined if adjusting your mixture screw is sufficient. Needle adjustment makes very broad adjustment. When adjusting deceleration needle, raising the washer creates LEAN CONDITION, lowering the washer creates RICH CONDITION. |
