Stihl 051 Carb Adjustment

[comoxmcgyver]

Hey all, I'm trying to determine which needle (slotted) is the high or low. The top one or one right below it. Which one do you adjust first, the top screw or the bottom. Hope that makes sense.... Can't find any diagram or reference to tuning this beast. thanks

There should be a letter on the carb either above and below each needle that is marked H for High, and L for low respectively. if not, someone here knows which is which.

Thanks, can't see which is which without popping off the top of the saw (not really wanting to do that if I don't have to) Thanks hope someone else knows.

The top screw is the high speed screw. Hope this helps.
