Thanks for the team.net link.
I don't know if I would prefer an analog gauge.  Checking the fuel mixture
under hard acceleration at high rpm requires checking the gauge out of the
corner of your eye, colored LEDs might be easier for this.
On my X1/9 I mounted the gauge "temporarily" right in front of me, up high
until I have the dual carbs dialed in.

I got my O2 sensor from Peter C. at a good price with instructions of how to
hook it up.
