Jim,
Make sure the rubber diaphragms are not torn or have no holes, even pin
sized holes. Also make sure they are seated properly, with the tabs in
the slots. It is easy to have them move a bit during assembly and not
have an airproof seal. Problems described above with the diaphragms can
cause the symptoms you describe.

Howdy folks,
It's me again. I am now having the fun of learning about Zenith
Stromberg carbs. I have new kits in both and mechanical functions look
good (not much wear at all). I can't seem to get them to work well with
the choke off. I pull the choke out 3/4 and they start great, but it
needs to stay there in order for smooth acceleration. If I close the
choke after warmup, I get sputtering acceleration. Is this caused by
fuel starvation via lean mixture? I bought the carb adjusting tool from
TRF but it doesn't seem to fit the carbs. I have the late model carbs
3771 from a 75 TR6. The tool has an allen wrench type head, but the
carbs look like they have a different type of adjustment when I look
down at the needle base. It seems like the tool should have a recess to
go fit over the adjustment "tab" in the carb. Am I making any sense?
Thanks in advance, only one week more to car show and car still not
ready!
