Non of that matters. The main problem is fuel and air distribution.
There is no way on earth that you can balance the correct amount of air and
fuel flow. I found this to be an impossible task - especially since i get
older and my hearing is worse since it has deteriorated due to the rumble of
the MG Jungle. I love to listen to that engine - the true identity of a
fine sports breed.
I have looked for more scientific and better ways to do the balancing since
the eyes and ears are fading quickly.
So I managed to buy a
_http://www.cbperformance.com/catalog.asp?ProductID=572_
(http://www.cbperformance.com/catalog.asp?ProductID=572) STE air flow
indicator - make sure you get the right size to fit your carbs. This site
is just one of many - so look around prices vary. About $30
This one single tool did more good in balancing air flow then any other
method I found before - and believe you me I tried them all.
The next thing I invested in is a Gunson color tune spark plug - I actually
bought two - to screw into each pair 12 or 34. About $30 ea
What this did was balance the flow of fuel based on the color of the
ignition.
What a remarkable and easy job it is to do this carb tuning and the engine
hums, Sings, PERCOLATES with the precision of a fine swiss watch. What a
difference I tell you, I am sold on this more scientific way and less on
using my worn out eyes and ears.
Use Google - Check out several sites - prices vary also try Amazon and
Ebay. The color tune can be bought used - but the STE I would buy new since
it is a delicate instrument and should be in tip top shape to give you good
readings.
Good luck.

It seems that as long as I've had my '53 TD the spark plugs have fouled
on a regular basis. Last summer I had the carbs professionally rebuilt
and adjusted and expected that to solve the problem. But today I tried
to drive the car and it was running so rough I turned right around and
went home.
I pulled the plugs and found #3 fouled (black material between points)
and #4 somewhat caked with black material but not fouled. #1 and #2 were
black but not so bad looking. This is pretty much the same thing I used
to see before the carbs were rebuilt.
Carbs were rebuilt last September, 1300 miles ago.
Plugs were new last September, 1200 miles ago.
Ignition wires were new in 2007.
Distributor cap, etc. new in 2004.
So I'm wondering what I can do to reduce this fouling? Would hotter
spark plugs work; I'm currently using Champion L82YC. Would a sport coil
help (hotter spark)? And if so, I believe the plugs have to be regapped;
to what setting? Currently they are gapped between .020 and .022
according to the book.
Thanks for any help.
