Carb sizes

[danb@wv.MENTORG.COM (Daniel Boughton)]

Original bugeye's did have 1-1/8 su's.  I have the original split manifold
used to upgrade to 1-1/4 if anyone wants to buy it.

The problem with determining size on SU carbs is the bore is not the same
through the entire body (with the possible exception of HIF carbs).  If
you measure the air cleaner side it's generally smaller by 1/16 than
the manifold side.

I measure them like:

Bigger than 1-1/4 smaller than 1-1/2 = 1-1/2
Bigger than 1-1/2 smaller than 2 = 1-3/4.

Works every time.
