  Did you get one of those air fuel meters that connect just to the stock
O2 sensor? If so, be very leery of the results it gives. The stock O2
sensor is not very accurate, except right at 14.7:1. As for AFRs to play
with, mid to high 13s are a good number to start with. But the O2 sensor
isn't accurate in this region. If you try to set your AFR with one of
these, I'd have it double checked with a CO meter.

Its on top, between the fuel distributor and the air flow sensor plate.
There may be little plug there that needs to be drilled out.

Buy a new bentley, or a new girlfriend?

Do you have pix of this tubing to the box? Mines shredded, and I'd like to
put some sort of replacement tubing in there.
