Bill,
After owning an MGB-GT and a TR-3B, my understanding is the following. When
you drop the cap into the hole in the top of the SU carb, it will free fall
until the bottom reaches the oil, which resists it's fall. It's very easy
to feel this point. Fill the carb with damping oil until resistance is felt
when the bottom of the cap is about 1/4 inch above the point where it would
be if it were screwed down to the normal operating point. Use clean SAE20
oil. I use No. 20 three-in-one oil.

Subject: Dash Pot Oil
Is there a definitive formula for the AMOUNT of dash pot oil needed?
My references refer to 1/2 inch above this or 1/2 inch below that, or
" when resistance is felt and there is 1/4 inch below the
threads",etc.,etc.,. On my 1957 TR3 for instance 1 3/4inch SUs (HD)?
would that be 1/4 ounce fluif measure, 10 Mililiters, or what...?
Any ideas, sage experience, WAGs accepted.
