Dave,
Someone makes an adapter for Holly carbs
that allow on-the-fly mixture control. Not sure of who, but I bet a good speed
shop would know.

You just need 3.5 Psi for the Weber. Although I use 6 Psi in
the race car. And some carb tricks on top of that.
do you have any ideas on methods to lean a weber, or any carb for that matter,
for altitude mixture adjustment. I have heard of a vacuum line to the inlet
manifold thru a needle valve to the fuel bowl, then vary the pressure head in
the fuel bowl. And, jetting the carb at sea level with the choke on, and then
backing off the choke as the airplane climbs.
Any comments or suggestions?
