Jim, thanks for chiming in. It's been a couple years since I played with the idea of deleting all the lambda crap. I currenly run open-loop by simply unplugging the O2 sensor and letting the freq valve lock into whatever fixed duty cycle it is (I can't remember, but it doesn't matter).
I do know that when I unplugged the freq valve in addition to the O2 sensor, she ran really really lean if I recall and I wasn't able to compensate enough with adjusting the mixture control screw - so just went back to letting the freq valve buzz happily away. Back then you did a great job of explaining how the freq valve interacts between the upper and lower chambers of the fuel head (or something like that, again it's been awhile).
