the best overall performance . Gotta test it first on a local truck I built a 38DGAS/intake setup for ....

Re: Weber 32/36DGV verses the Weber 38DGES
Just so you guys know I still check this forum daily. I have been watching this thread for updates.
I bought a used 38DGES off ebay last week. It MAY need a rebuild. How hard are these things to rebuild and is there anything I
should look out for?
The carb came off a 73 landcruiser. Is the baseline jetting on these things that different between applications? Will I need to rejet
it? (If I need a rebuild and a rejet it may not have been such an awesome deal then.)
I am awaiting an engine swap in the next few weeks before I install the carb. Very soon after it will be time to install the LC
Engineering header in my garage, along with 2 1/4" piping (as long as that is reasonable).
Thanks, and keep the good information coming. I am glad other people are learning some of this valuable knowlege.

The 38's have some inherit problems with the throttle shaft seals that should be addressed. Some are not installed correctly at
the factory but this does require removing the throttle plates and completely realigning them . If you've never done one, let a
rebuilder do it or you risk permanent damage . There are the nylon wrap bushings as well as the nylon ring seals on those throttle
shafts , some are a real pain to put together . Also, the gear drives have to be re-timed to make it work right at idle . The Cruiser's
jetting is a bit different , just have to try it and go from there . You will see quite a gain in torque over the 32/36 for sure....

Hey Ron,
cool, so you finally got one.
rebuild kits aren't too expensive and are pretty simple, really. haven't done a Weber one yet, but I think all you'll need really will
be a new cover gasket, needle valve, and a couple of other gaskets. I'm not sure if there's an accelerator pump diaphragm or not,
but it looks to me like the Webers are a lot simpler to rebuild than the stock ones.
jetting's no big deal.
I guess the best thing to do at this point will be to pull the top cover and make a note of which jets it's got in it right now.

so I've been running the mechanical distributor, as you know.
I like the response, but I still can't call it properly tuned.
it's definitely the most responsive it's ever been. it pulls hard in the primary up through & past 4500rpm, due mostly to the Ramflo
air filter. when I bring in the secondary, there it pulls harder.
I am having a problem, however with pinging on the wider open throttle positions. it pulls nicely, quietly on mild throttle, but
opening it up whether at sub 3000rpm or on hard acceleration pass 3000rpm on up, it pings pretty hard, especially when under
load.
I have to document the ignition curve I'm getting with this distributor and hope to get around to it this weekend.
LC recommends base timing of 10*. retarding the base timing to 8* doesn't help with the pinging. going to 5* does help
somewhat, but anything lower than 10* and the response just isn't there.
I have considered fattening the fuel, but not quite sure how to go about it and whether the response would suffer. I have tried a
140 main, but it just got sloppy.
right now I'm at:
idles: 75/60
mains: 135/150
airs: 180/175
I guess I could try like a 145/200 main/air combo to see what happens. I have tried just fattening the main jet, but response
suffers so I think I need to bring up the air jet as well to compensate, but this will delay the influx of the main circuit, won't it?
