Hi Folks:

I have the Hummel 32 HP 1/2 VW with the Zenith 12566 carburetor (68 series). The guy who owned the plane before me, his airport was at 50 feet above sea level. My airport (Seeley Lake, MT 23S) is 4250 feet.

I don't have a manual for this engine ... and I don't know if Scott even makes one. Can you tell me the procedure for adjust the main and idle jets? I know the idle jet gets richer when you screw it in (clockwise), which is opposite of what I'm used to. I don't know about the main jet.

How do you recommend I adjust those two jets?

Thanks!
