cool.
have you gotten a cable measurement yet?
sorry for dragging my feet on this one. my truck buddy's only around on the weekends and we haven't been able to hang out for a
while. I can get one of the guys from the office to help me, though.
Re: Weber 32/36DGV verses the Weber 38DGES
No, the only real thing left is actual cable stroke, or distance the cable travels as the pedal goes from idle position to full throttle.
That will be the final distance setting from the cable mounting bracket to the throttle wheel mounted on the carb's shaft . Also,
does anyone build a full mechanical distributor for the 22R's? If not, I will be forced to modify the carbs and install a vacuum
advance port since almost all models of 40-44mm DCNF's do not use them . Like I said, hope to move very forward with this
project early next week...

LC Engineering makes a mechanical distributor. I think they're around $270. I bought one a long time ago, but switched back to
the stock type for the time being.
Re: Weber 32/36DGV verses the Weber 38DGES
Ok, so I doubt they are real common . Just needed some info on whether or not I had to set the carbs up with a vacuum advance
. No real big deal, but may add a bit to the overall cost . Hoping to keep the prices fair as possible, probably just find used carbs
and rebuild them since there are no major wear issues w/DCNF's.

you know, do you think you could just rig up "ported" vacuum through the air cleaner assy? or do you think that signal wouldn't be
strong enough?
Re: Weber 32/36DGV verses the Weber 38DGES
Not enough signal, vacuum advance units typically require 10-15"hg to actuate them fully. I'd hate not to give the ability to use the
carb to it's full potential. Adding ports is not that bad, just gotta know where to time them...

Re: Weber 32/36DGV verses the Weber 38DGES
how do you mean... where to time them?
how can you control that?
Re: Weber 32/36DGV verses the Weber 38DGES
The relationship between the throttle valve and the hole for the advance as well as angle/size will determine the volume and
timing of vacuum applied to the advance line.
For example:
On these Suzuki's the advance port at the distributor is 1/8" . Almost all of the Webers use a 3/16" advance port at the carb . I
can actually test a difference in ignition timing advance and how fast it opens by altering the length of the vacuum advance line
and how far I run the 3/16" tubing before adapting to the 1/8" tubing . If the 3/16" piece is pretty short, the timing jumps up pretty
radically . The longer the big tube, the slower and more stable the timing reacts . Almost sounds nuts, but the carb works the
same way . If that port is drilled too high like a lot of the Holley's the advance becomes a bit sluggish. If it's too low it can also
exhibit a quick initial pull but will drop off a bit as the blade is opened . There is an ideal spot but each carb is different according
to the throttle blade angle . Webers that I use for the most part have 78* throttle blades which makes it pretty easy to align the
port timing . Specialized tuning is fun but can drive you a bit nuts at the same time .....
BTW, done with those emulsion tubes yet ?
