Nat, I don't think that's correct. The topper tank helps hydraulic flow by 
serving as reservoir just behind the FW. Although it's small, that's all that's 
needed. Once flow is established, physics will feed the topper tank if the 
pipe pressure is applied to the main's vent. Fuel to the engine doesn't have to 
overcome as much friction coming from a shorter distance, for verticals in 
particular.

BUT, if  the ventury is small enough, it would matter less, and the engine 
would likely not lean out in verticals. For typically sized venturies on the 140 
sized 2 cycles tending to run around 0.375"-0.400", a topper tank settles the 
verticals down alot

as always, open to differing or opposing points of view

An aclimation phase and a learning phase and some money! On another subject, 
the physics say a hopper tank is of no value. What do you think? Is there a 
momentary value? Karl - bypass the hopper tank and report!      Nat
