>OK, so I'm in the middle of a carb rebuild on my "72 TR 6 and I find that
the
bypass valve diaphragm on the first carb seems to be marginal (still moves
but seems to be a bit brittle). The rebuild kit I purchased locally
doesn't
have a diaphragm included. My question is, Do any of the rebuild kits
offered by the big three include this? Or, How critical a component is it?
If I just carefully reinstall the old diaphragm along with new gaskets will
I
notice a major difference in performance?
My reason for doing the rebuild was to try to cure a rough idle and
inability
to get mixture settings correct. Could this be part of my problem?

Micky, as a test you can cut some gaskets for these valves out of flat
gasket stock that contain no holes and will effectively block off the
ports. I did this some 12 years ago and so far the test is going well.
;-)
This can tell you if the valves are the cause of if you have other problems
as well. Another issue I had with my TR6 was the emissions hoses to the
canister. Even though they looked tight, my rhymic hickup in the idle went
away when I replaced these hoses with fresh.
