Have you checked the float level in the carb that is leaking?

Subject: [TR] SU Fuel Problem
A friend of mine is having problems with his SUs that we just can't figure
out. Here is what he is experiencing:
My 1970 TR6 is seeping fuel out of the rear SU float bowl overflow tube.
The SUs are a new Moss Motors conversion set. I called Moss about the
problem, but they were no help. I installed a heat shield, but that didn't
change anything. I installed a new Moss fuel pump, but found that it was
putting out 7 lbs. of pressure. I next installed a fuel pressure regulator
and dialed it down to 2 1/2 lbs. I thought my problem was solved. Today I
drove the car 140 miles in 86 degree weather. While driving I thought I
could smell fuel and when I returned home, I popped the bonnet and could see
fuel dripping from the overflow tube and it continued to do so for a short
time after the engine was shut down. Anyone have any ideas as to what is
causing the problem and how it can be solved? I am stumped.
Thanks.
