Sorry, Daniel-
I had to be "short" on my last reply 'cause
Seinfeld was coming on, and I cannot
miss Kramer and/or Neuman!
Do not worry about a "contest" of any sort
here. I know you from the site and can
accept an honest error, whether it be on
my part or your's; no problem, either way.
Now, I have not run a Weber since my
"tuned" 1311 went away years ago and
I replaced it with a stock SU equipped
'67, which got a Judson later on. When
this car got destroyed, I picked up my
current 1098 (stock) equipped '61 Frog
which is getting a Judson-tailored 1293
and the Delrin-vane equipped overhauled
Judson after initial run- in on stock SU's.
So, I've been out of the Weber business
for many years. So, could I be mixed up
in memory after so many years? Sure!
When dyno tuning my prior 45DCOE
equipped tuned 1311, the operator-
tuner weakened my main system for
better economy and made up for slight
leaness on the "top end" by increasing
the size of the accelerator pump jet
from 50 to 60; quite a difference.
But, it worked on the dyno according
to the CO readings, and cruise economy
subsequently increased without any
"drying out" on the top end. Got 60K
out of that 100hp+ motor before it
dropped a valve taking off gently from
a stop lite one day.
So, technically I may be wrong about
exactly how the "balls" fit in to the
entire scheme of things but in practice,
there is no doubt in my mind that the
accelerator pump circuit is involved
in mixture strength at the top end of
the rpm scale as high speed flow
"pulls" fuel from this opening on it's
way through the barrel into the intake
manifold.
So while operationally correct, I could
very well be technically wrong? Yes!!
Now, I am gathering up all my Weber
stuff to send to Mike Maclean out in
California. As I gather this stuff next
week when I return home after my
next trip with the airline, I shall no
doubt find my old Weber books and
shall look through them, accordingly.
After which, I shall again contact you
after "re-educating" myself, so to speak!
In the meantime, there are two little
balls in the little monster, for sure.
I thought I knew their function, but I'll
re-check as aforementioned.
Cap'n. Bob
