Well, Jim,

Though I have read Veedubbers treatise on the progressive carb, I still find
the advantages of the dual carb to outweigh the disadvantages.  The
elimination of carb icing is the main one, though I think the performance of
the dual carbs is almost as helpful.  It is true that changing plugs sucks,
but the amount of pull up hills, and overall performance I get with the
duals is worth it to me.  It is also true that with a single progressive you
can use the stock air cleaner, keeping fumes out of your engine and cabin,
which is a silent but notorious problem with duals.

Eug,
