Just to speak from the opposite side. I have a single, 2 barrel progressive Solex carb
on my Canadian  91 syncro westy and I am very pleased with it.There is no
perceptible difference in how the van runs,  and I get the same MPG as other syncro
westies.  I had the emissions recorded and posted the results to the list (
http://gerry.vanagon.com/cgi-bin/wa.exe?A2=ind0005B&L=vanagon&P=R30979 )  As
I recall it was not so 'dirty'.  Also, any emissions study will have to include all of the
diagnostics & replacement of EFI stuff (that constitutes about 20% of the discussion
on this list).  also carbs 'wear' slowly over time and don't 'break' so I hope to get
some warning prior to being stranded.   Malcolm
