Need some help for those who know how to adjust the carb on this older model - Stihl 031 AV. I just rebuilt and have no manual to help with adjusting. It is a Walbro with a H and L plus an needle that one can adjust inward to open/adjust the throttle in more.
Here is what I do: First - Screw H and L all the way in and back-off both H&L 1 full turn. Start saw. Chain is really moving fast/oil coming out on bar. I slowly turn to the right the L (one next to combustion chamber) until the chain is almost stopped or barely moving. Next I trigger saw to test high speed. Saw bogs down when I try to rev saw up to check high speed and usually stalls out. :bang:
When and do I use the screw-in needle adjustment that can hold throttle open?.
Thanks
