Subject: About the single Weber! My conclusion...
Note: this is stuff for the Aircooled guys... but it's good to read to...
This Carb (The single progressive Weber) was on my garage shelf since a
bought it in California (last trip to Mexico-USA)
It was tried in CA without any success, now I can say for sure that the carb
was NOT the problem then, I apologise to the one who sold me this one!
Since I bought my bus last September, I was aware that my old Solex were
going away, even after many rebuilt and new parts (butterfly bushings) they
still gave me a hard time once in a wile, well, I should say very often!
(Very difficult start some morning with heavy backfire, some day it was
engine hesitation at low and medium speed). Many of you guys and other guys
from other list told me to get rid of the Solex, I didn't do so, I was
stubborn and I was sure I could rebuilt those old carbs.

I was wrong, A 30 years old complex part will always stay 30 years old.
So lately my decision was to go FI, so I bought a complete used FI ands
fully restored that one, but it was not completely finish + some testing
were needed before I do another big trip, am in Montreal so summer is
short... OK, so as summer is going fast and my girlfriend want to use our
Bus with her girlfriends, and on top of that the bus gave me a lot of
trouble last weekend in Maine, I've decided to try the very SCARY single
Weber before I buy a twin set of 40mm. I heard so many horror stories about
the single that I was somewhat scared of trying this one + it didn't work
when I was stuck in CA (San-Diego). You should know that this one didn't
work because I had water in my tank at the time and no compression on #2-3-4
(0-PSI!!!)
Here we go, I changed (45&50) the idle jets for some good average one (info
sent by some good and friendly S-Weber user), so a 65-PIJ (primary idle jet)
and a 50 SIJ (Secondary Idle jet) were use for a start. Removal of the old
carbs + installation of the new Weber took 2 hours (rerouting the cable
included), I stated the bus and.......vroummmmmmm on high idle -choke close
- cam on, 1500rpm steady, after the idle went a bit high I press the pedal
and it went to about 1100, I went into the back and started playing with the
mixture screw, like stated buy other: always play between 2 and 3 turn, if
you need to go lower or higher you need to change the idle jet, well I
didn't! After putting that screw a 2.5 turns and playing a bit with the idle
mechanical screw, bang I was at 850-900rpm, STEADY!!!
So I played with the gas and I saw that I had good acceleration and
deceleration, time for a quick ride...
For those who read my Mexico trip http://www.eurokitplane.com/intro.htm
(not finish but will be soon)
you probably know that my trip was a nightmare mechanically, or should I say
that since I owned that bus it was a mechanical hell, especially dealing
with the carbs.
After my top end rebuilt the bus was almost perfect, I couldn't believe how
powerful a Bus could be, BUTTTTTTTTTTTTTTTTTTT.... I was still struggling
with the carbs.
After a 30 miles ride in town and freeway, I came back home crying!!!
Eureka!!! Finally I had a super powerful running Westy (I was ready to sell
that bus)
I couldn't believe how sooth running was the Weber (forget about the icing,
don't spoil my happiness for now), very stable idle, EXTRREMELY good
acceleration, low, medium and top end. Head temp still at 350F steady at
60mph, oil 210F. That bus is screaming for a 5th gear. I truly cannot belive
the power I have, this thing is pushing more than my Vanagon 2.1L. (It's
only a 1700cc.... Oversize!)
I heard so much "Bashing" about that carb that I was sure it was pure crap,
it is NOT!!! So before any of you guys "Bash" the Single Weber...you should
think twice, I did a 100miles tonight in that bus, for the first time I was
in peace, I could have driven that bus all night. I don't say that it won't
do some icing in cold weather or you could need some small jetting, but it
is a fine little carbs for the price, let me tell you that.
Best regards, Ben
