>From the description you give, it sounds as if the float level is a tad high.
The bolts you tightened were the ones that simply hold the choke and auxillary
venturi in place. The bolts are pointed on the end, matching indentations
in the venturis. On the 40 DCOE a small pin is used to locate them in the
proper orientation, and the air horns or filter backing plate hold them
in place.
What is also a possibility is that the chokes are too large and at low revs
you aren't getting good atomization of fuel, but droplets falling into the
bore. And when these drops get to the bottom of the bore the fuel either
drips out around the locating pins or runs down the bore into the manifold.
As to which direction to turn the idle adjustment screws, I'd guess either
left or right. Helpful, isn't it? The idle mixture adjustment screws on
a Weber control the flow of gas through the idle circuit, unlike say, the
Stromberg CD which has a screw controlling the air flow. So turning the
screw in (clockwise) reduces the fuel flow, leaning out the mixture, turning
the screw out or counterclockwise will enrichen the mixture. I'll leave it
as an exercise for the reader to figure out which way improves the MGB idle.
Bring it by the Fat Chance, we'll look into it!
And a quick note on fuel lines, you can get Earl's "Tube Mate" hose ends
which fit over the inlet tube of some carbs, allowing the easy hookup of
Earl's hose and hose ends to carbs which do not originally have threaded
inlet fittings. The selection is limited, allowing you to mate -4 hose
to 1/4" tube, and -6 hose to 5/16 and 3/8 tube. All configurations are only
available in straight hose ends, which means putting -6 hose on the twin
Strombergs of a TR-250, for example, is a bit tight.
