How will I know when I have turned this little guy too much? And when it shuts off and on does that mean i rev up and down really quickly (2x a second) or slower (2x every 5 seconds)???

If you could just give me your thoughts...

 

When your motor doesnt die when you turn the AC on its fine

I had mine set at about 1200 or so... All it is a vacuum diaphram that opens to put a little presssure on the throttle.. Adjusting it wrong will either stall the motor upon AC operation or rev to high, Very simple to adjust
Once the motor gets to 1500 it shuts the valve off, thats why its cycling like that
