WEBER EMULSION TUBE F11 – We have found these to work quite well in our dyno testing of Rotary race engines.
(2) Needed per carb.

We also like to use the F8 Tubes. Changing tubes can really change the fuel curve.

Weber tubes are kind of a “black art + luck + voodoo” — by far best to test on a dyno with a wide band O2 to see fuel curve. Remember Rotary engines like to be pretty far into the rich “zone”. A page from a Weber manual showing the number of holes, size, and location is attached.
