Tilting the Bing to deliver more fuel to the lean side of the engine can be thought of this way; Fuel enters the airstream from the atomiser and needle at the 6 0clock position. By tilting, you are moving this discharge of fuel closer to the side that is lean, basicly, fuel bowl (bottom of carb), towards the hot side. The reason why this works is because there is a divider in the intake manifold and by moving the atomiser to either side will bias the fuel into the airstream versus straight up plumb position.

Try searching for a thermostatic oil cooler bypass adapter. It replaces the oil filter adapter you currently have. Leave it on winter and summer, no tape, cardboard. My oil temps stay around 95 to 100 C to cook the moisture out. Try this company - www.thinkauto.com

Recently I cleaned the main air bleed of any roughness by pushing and pulling a drill bit by hand, like you would with a file. I also chamfered the air entry of the bleed port. The holes of the atomizer were also opened ever so slightly using the same technique. Doing all this improved cruise fuel consumption with fairly even EGT's 1310 to 1325, about 2.5 gal per hour. 3300's air bleed and atomizers are actually drilled significantly larger as their air pumping is half again as much as our 2200's. The splitter is swaped with a round bar.
Changing throttle blade angle and the fact that fuel is entering the airstream not far ahead of the splitter does not give much time for fuel to shear and mix with the air. The splitter seems to have two functions, to add separation to the air/fuel mix and to increase velocity to help shear up the fuel. Often wondered what would happen to the fuel air mixture if there were angled grooves cut into both sides of the splitter, just like VG's on a wing or, a circle of small VG's just inside the outlet of the carb. .......They don't call the experimental for nothing!!!.....Don
