Who did you talk to ? Give me the number and name and I'll take care of that issue real quick. Already have a good
idea of who it may be , just verify my hunch.
The 38DGAS for your engine should have:
55-60 idle jets
140 mains
170 air jets
F50 tubes
This is assuming you have the model with 27mm venturis . Check www.piercemanifolds.com for a drawing on the
DGV float height . There is a drawing for both the plastic and brass floats. If the motor won't idle when cold there's a
chance the choke setting is incorrect or the choke blades are jammed shut . As well, the idle jets could be blocked
too. If you need help, shoot me a pm and I'll give you my phone number.

Thanks Sarge.
I wish I had asked for the guy's name. I didn't even write it down. I got the guys number and extension from a tech at
carbs-unlimited. I'm going to tinker with it today a little and see what I can do.
Re: Weber 32/36DGV Tuning
The 155 mains are way huge for that motor . Actually, they are sort of big for the Cruiser's six as well.
I know pretty well who you are referring to, got some plans for his attitude real soon. I used to get most of the tech calls for
Redline if anything was ever mentioned about DGV's, jetting or offroad use . That tech has since moved on, the guy that replaced
him is good to deal with but his boss is an a$$ of the highest degree. No wonder they keep losing all their good people .

Re: Weber 32/36DGV Tuning
I had a response written up last night, but got those wicked sql error when I tried to post it.
anyway, I was saying those 155's are a bit big for the 20R and that most guys are only running 145's on their 38's for the 22R, but
still, it shouldn't stop it from running.
I'm thinking there is a blockage somewhere.
when you received this carb, did it look like it was cared for? was it wrapped up or sealed somehow? my 40/40 sitting in its box in
the garage is wrapped in a towel at least, though a plastic bag would be better.
have you pulled it apart to check it out? looked at the jets?
isn't there some kinda diaphragm on the sides of them? what happens when it's dry rotted or torn?
basics... I'm sure it's something simple.
once you get it running, then we can start looking at the tuning aspects.
Re: Weber 32/36DGV Tuning
Alright,
I talked to one of the techs at LC Engineering (John) and he gave me some numbers to work with.
The numbers seem conservative to me, but here they are:
mains 140
idles 40
airs 190-195
86 of 88
