Is he running an electric fuel pump? If so is it a 2 - 3 PSI unit or the h=
igher, more common 5 - 7 PSI pump? the higher pressure may be overcoming t=
he 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 f=
orward 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 in=
to the engine. So I replaced both float valves with standard valves and als=
o changed both floats. After putting everything back together, I ran the ca=
r for a few minutes and turned it off. It was dripping gas out the same por=
t. 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 correc=
tly. 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 fl=
oat to fully close the valve when the mold line of the float was parallel w=
ith the horizontal edge of the carb where the fuel reservoir attaches.
Am I missing anything else here?
Thanks
