>What are your thoughts on something in this breather 
system fighting each other? That is to say... the float
bowls being effected by vacuum from the valve cover
or fuel tank vent.

If the fuel tank vacuum created as gas is extracted, or the 
crank vacuum pulling on the canister were to create 
a small vacuum in the float bowls, does it sound feasible 
that this would effect the gas level in the float bowls 
which would explain why pulling the choke to compensate
for the level in the jets makes it run better.

Paul,

The canister should have a vent on the bottom side to atmosphere that will
accomodate any reasonable amount of air flow to/from any of these devices -
unless the canister is plugged up.  If you have a working canister then
there is no pressure differential to ambient.
