Hey Joe,
Give Jim Cline a call, he's really helpfull and a nice guy to talk to on the phone. I really had a jard time ponying up the bucks foir that little part but seeing it in action made me forget all about the cost.

The Cline is pretty easy to use but take a modification of one's thinking once you decide to put one on your engine and actually use it. Basically the low end needle is set like always but the high end needle is pretty much not even needed once the regulator is on the plane. The reason I say this is that most people that are new to these can't understand why their high end adjustment doesn't seem to "adjust" after putting the regulator on. Screwing the needle out seems to have no effect as the engine doesn't get blubbery rich like it did without the regulator, and this is as it should be! What you are seeing at that point is the regulator doing it's job, metering only what the engine demands, as it demands it. You can still lean the needle out but attempting to get the customary 200-300 rpm rich setting can be impossible on some set ups that I have tuned. My rule of thumb on thse is to set the low end and then go full throttle and lean the top end, then back off till it's as rich as it will go and then a little more, then fly.

It really is pretty simple, once we stop MAKING it hard!

Thanks for the kind words
