goofing off with the maid !

While true that the heavy damper oil will richen the
mixture, it also restricts the airflow.
I believe the Spit Comp manual suggests running the
dampers empty, lightly lubed with 3-in-1 oil or equiv.
We ran them this way on our G-Prod Spitfire.
There is an element of tuning here. Depends on carb
springs, needles, jetting, and engine mods. The
damping effect should match the responsiveness of your
motor, giving initial richness, then opening up as the
RPM climbs.
Use a G-meter, stopwatch, or dyno to find out what's
best for your setup.
