Try this for your next  go round.  Given your intimate knowledge of all the
screws you might be able to try this with the carb still on.

Either loosen all the screws a bit (if the carb is still attached) or snug up
all the screws (if you've pulled the carb and are now resealing the gasket), but
when you give them that final tightening make the corner that is leaking and the
corner diagonally from it a little tighter and leave the other screws (next to
the leaking corner at 90 degree angles) not quite as tight.  The theory being
that the float chamber may have a slight bow in it that is "lifting" the leaking
corner.  Hope that makes sense.  This is a long shot but maybe worth a try.

There is supposedly a tightening sequence (I think in the Haynes carb manual). 
But when you look at the diagram it's blank.  Does any one know what the
tightening sequence should be?  I just do an opposite screw tightening sequence
for lack of the real thing.

Hope all in the NE had a chance to get out with the 
top down today. It was beautiful!

I (my TR6, before the wise guys/gals come back with
a zinger ;-) ) have been experiencing a slow leak in my
front carb that just won't stay dry. I have removed the
carb twice now and replaced the gasket and used 
gasket sealer that is resistant to gas. Both times the
leak was in the left back corner at the point of the 
screw (from the pont of looking at the carb with it 
still attached to the intake manifold). The first time
there was enough of a leak that it dripped gas. After 
resealing the carb it held for about a week but started
leaking again. The second time I resealed the gasket and
it held for about three weeks, including a 400 mile drive
to Britain on the Green at Woodlawn and a nice visit
with Fred Thomas and his wife.

After a long drive today, checked the carbs (yes, I've gotten 
a bit paranoid) and sure enough a very slight film of gas
on the float chamber. After further inspection with the 
trusty mirror, it is a very slight seep from the same corner.

I have become very proficient at removing the carb and will 
reseal the gasket for a third time. Am I missing something here?
I have adjusted the float but could the chamber be over filling?

Any help would be appreciated.
