So, i have intermittent loss of power under moderate to heavy
acceleration. The engine basically stalls, until i get most of the way
off the gas again, but it doesn't do it every time, and even when it's
doing it I can usually get on the gas for several seconds before the
'power goes out'

I'm pretty sure it only happens when the secondaries begin to open,
and once I thought I heard a tailpipe detonation. So, maybe mixture?
What do? (could it be a vacuum leak? an issue with the timing?)

Problem #2 is that the air compressor only functions intermittently.
It seems that the compressor itself is fine, and that the problem is
the pressure switch on the tank. It seems that it works most often in
cool/damp weather. Probably I can solve this problem with a
multimeter.

Halp?
