it just has a round slide and a spring in it, not sure what it does though. looks like what a choke looks like even though it's not the choke.

I would take it to clockwise raises the RPM and Counterclockwise lowers it, but does anyone know how to tell what RPM you are at when setting this

put your lips together and pucker up. then take your index finger(right or left, whichever you're more comfortable with)...make a fist and extend only your index finger. while holding finger horizontally, touch it to the middle of your "pursed lips" then move your finger in an "up and down" motion against your lips as fast as possible while making a soft humming sound.

as you increase your speed, raise the pitch of your humming. If you do that as fast as you can...that will be approximately equal to 500rpm.

...p.s. do this either inside the garage or inside the house.(neighbors) :rock

There is no way to "Know" the RPM's without a tach.
