air compressor governor question
how can I adjust the pressure the governor allows the compressor to build? I installed a new compressor yesterday, and at first the pressure would build to 130 psi a few times (which is high I know) but now it will only build to about 110-115 (the 2 needles aren't even with each other, never were).
I removed the plastic cap on the end of the governor, and there is a lock nut and the bolt has a slot to turn it. I'm guessing thats all I need to do, BUT if I push on the end where the bolt/jam nut are the whole inside of the governor moves, like there is some free-play in there. do I have to set it at a certain free-play, or just adjust the bolt/jam nut to I get the desired pressure.
I know this is probably easy but I don't want to screw anything up.
