<VV> Individual carburetor air cleaners

[UltraMonzaWest@aol.com]

Folks,  the SMALL  tube [ tee]  is the Positive Crankcase device! [ 0.064"  
orifice / hole].

Do NOT  plug!.....

The large tube to the Air Cleaner is the Fresh-air INTAKE and EXCESSIVE  
pressure / blowby  VENT.

It should go to at least one of the Primary Carbs' air cleaner [ inside the 
filter ].

If you engine is in good shape it can be vented to atmosphere....with a 
filter of some kind to prevent debris from entering...but MOISTURE  is the main 
reason for being inside the AF housing!

If your engine is "tired" [ worn rings / lots of blowby during high rpm 
running ]  then you will oil your shroud / fan / barrels, etc..UNLESS  you put to 
the air filter!
