Carburetor Leaning out on Long left hand sweeper

Thank you for walking me through some good ideas. I do not have jet extensions but will buy some along with a new road race float to accomodate them. Vector1 - how streetable is the 1:1 linkage. I know that is subjective but would like to hear your thoughts. I actually already have a little baffle that covers the power valves and keeps the inlet sucking fuel from the bottom of the bowl.

I'd get rid of the "spring loaded" needle and seats, and fit normal .110-.130 viton tipped needle and seats. Check and adjust float levels.

Fit road race floats and fit jet extensions to the rear with a notched float in the rear bowl.

The jet extensions only help under hard acceleration when the REAR bowl volume can uncover the mains/pvcr.
No benefit fitting extensions to the FRONT.

Can't remember why I tried it but haven't noticed any problems. One way to look at it, with the secondaries opening with the primaries it might be easier to modulate than having the secondaries opening with the last of the primary opening. Our cars are so light you possibly could not be into the throttle as much as you think.

Something else you might check is your amount of ignition advance. If you have a vacuum advance hooked up, unhook it and the effect will be to richen the a/f ratio I believe.
