I seem to average in the upper teens. Pretty much the same reason, it's so fun to romp on the pedal. Below 3000 rpm there's more noise coming out from the carbs than there is from the tailpipe. Then the exhaust takes over.

I used to have a wideband O2 sensor and gauge on the car when I first installed them, to help with the jetting. Any time you tried to lean it out some, they'd get all snorty, lots of little wheezy backfires. Running nice and rich (12:1 or so) they are as happy as can be.

BTW, the O2 gauge showed them to be pretty erratic in terms of fuel delivery. Lots of things could upset them. Going around corners, for example, lean one way, rich the other. Go over some bumpy pavement and they spike rich.

Great for just occasional 'spirited' driving, I think if I was daily-driving the PV I'd stick some SU's back on it.
