I've got a couple of Bosol (Brazilian) Solex carbs on my '74. I bought 
these from Bow Wow incidentally. Because they came from Brazil, they are 
apparently jetted for methanol and run really rich on gasoline. I have been 
unable to find any replacement jets for these carbs. Bus runs like a bat 
outa hell, but only gets 14 mpg and won't even come close to passing 
emissions testing. I bought a couple of used Weber 34 ICTs that I'm going 
to try out. I've never heard of running dual Solex's on a 1600, but that 
doesn't mean it can't be done.

Subject:      '71 with Kadron Carbs

I have recently acquired my second '71 Transporter/Camper. It comes with a
fresh, stock engine (Tom Noble) and a pair of nearly new carbs, presumably
Solex, sitting on Kadron intake manifolds. The previous owner advises that
the carbs are too rich, to the point of jeopardizing the lubrication of the 
engine, and that the tank is so fouled with rust that he has needed to
replace gasoline filters on a regular basis. The bus came with 1/2 dozen
extra filters.

I've adjusted the timing to specs, 5 deg. ATDC, and checked the advance. I
tuned the carbs as best I could using installation instructions given to me 
from the files of a local supplier : Autovice/Bow Wow.  These are all
verbal, no pictures, and don't seem to exactly match what I see. What's
more, the instructions say that the particular Kadron/Solex combination to
which they apply are not suitable to engines with compression ratios above
7.0. The VW service manual gives the 1600 engine's compression ratio as 7.5 
!

The engine backfires occasionally and the fuel flow to the carburetor
appears to be weak, but the translucent in-line gasoline filter seems 
clean.
On my first trip out of the driveway, I needed a tow home. It died in a
cloud of smoke after going approximately 3 miles. The spark was present, 
but
the engine wouldn't fire. It started running again, by itself, but I 
haven't
ventured far since then.

I plan to check the fuel pump next. At the same time, I need some info on
the carbs, please.  Are they appropriate to the engine? How does one
identify them? Tune them? Are they worth keeping. What jet size is
appropriate? Is there a place to write for manufacture's information? Any
advice would help.
