Dave,
You are probably on to something here. The car is a 76. I will be at the garage
working on the carbs again today. If you have a free minute to talk some time
today, give me a ring.

What year is the car? In the 73 and later cars the carbs have a valve that
diverts the float bowl vents from a port on the face of the carb (air filter)
to a port that is connected to the charcoal canister. These can get stuck in
one position or the other and the canisters often clog or fill up with gas. Or
the lines get plugged. The diverter valves will open the port on the faceof
the carb when the throttle is off-idle so see if there is any difference when
the throttle is cranked open.

Adjusted the floats. Pulled the chokes to get started. Cranked a few times and
didn't start. Figured it needed fuel pumped. So I pulled the manual lever to
fill the carbs. Stopped pumping when I saw gasoline squirting out the choke
(enrichment) valve. I am confused about what could be going on here. I have
other carbs I can pull the valve and trade. But that may not be the whole story.

Another possibility is if the float bowl vents are clogged there is no place
for the air to go and the floats will never rise up to shut off the gas flow.

Ditto Dave.
Just had that same problem with a recent non-TR acquisition. PO had installed
the higher pressure pump and the car instantly flooded as soon as it was turned
off. Much fiddling and head scratching before I replaced the fuel pump with a
2-3psi Facet and problem was solved.

Is he running an electric fuel pump? If so is it a 2 - 3 PSI unit or the
higher, more common 5 - 7 PSI pump? the higher pressure may be overcoming the
float valves.

Subject: [TR] TR6 Stromberg question
My friend's TR6 was running poorly. After the car had been running, and was
turned off, I noticed drips of gasoline dropping from the port below the
forward carb just in front of the intake manifold. I concluded the Gross jet
was not stopping the flow of gas to the carb and gas was getting pushed into
the engine. So I replaced both float valves with standard valves and also
changed both floats. After putting everything back together, I ran the car for
a few minutes and turned it off. It was dripping gas out the same port. Looked
in the throat from the air filter side and saw a small puddle of gas in the
lower area right in front of the venturi. As far as I know, that means the gas
isn't shutting off. Perhaps I didn't adjust the float correctly. Or there is
something at the fuel inlet orifice allowing gas to bypass the valve. Is there
anything I am missing here? Could the enrichment valve (choke) be the culprit?
I haven't touched that yet. I adjusted the new float to fully close the valve
when the mold line of the float was parallel with the horizontal edge of the
carb where the fuel reservoir attaches.
Am I missing anything else here?
Thanks
