Removing Tri Carb Air Cleanerws???

[Lee Mairs <lmairs@sagcorp.com>]

I have a BT-7 tri-carb that has been lying idle for two years now.  The 
other day I tried to remove the air cleaners inorder to inject carburetor 
cleaner, but had absoultely zero success.

Is there some sort of magic tool, shortened wrench, bifurcated ultra thin 
socket that is necessary to do this job?   How can it be done without 
removing the all three carbs aswell as the throttle assembly?
