Bill, There is a difference between the Lambda version and Non Lambda for
the FD. I just had my builder build a Non Lambda version for a turbo
delorean out of a Volvo Turbo dist that has top port adjustments. There is
more to it on the inside than you think for fuel flow.

"Rich, cross over to the Dark Side..."
Unless somebody can explain otherwise, makes sense that removing
frequency valve altogether will simply allow upper chambers to flex to
maximum size (as if Lambda were metering rich) and stay there. Could
then adjust CO2 screw accordingly.
May be a metal plate in my R30 distributor too, just without any sort
of access to its underside (lower chambers). Am not about to open the
thing up to find out.
Distributor on my new engine looks just like stock DeLo. Even has port
for a frequency valve (you of course have the valve itself -- keep
it). If I can block the thing up well enough at home to run on the
ground will experiment with de-emissioning and post results. Anybody
have an old fuel pump I could borrow?
