Rich = drop below idle after blip - try 1/2 turn in
Lean = hanging above idle after blip- try 1/2 turn out.
This works real good , check it out. http://www.factorypro.com/tech/carbtun.html (http://www.factorypro.com/tech/carbtun.html)
great ..glad i asked ..i was thinking it may be lean ..wrong! ... thanks for the tip and the link!
If you read about the blip test then follow the process to by certain you're adjusted correctly. The last time I adjusted my carbs the response was opposite that described above. When I turned them too far in I got a bog followed by a drop in RPM. Too far out and the RPM would hang.
That's why I always encourage people to follow the full test to make sure you get the best results. Only takes a few more minutes. Why guess when you can be sure they are adjusted correctly?
