Once the SU carbs are sorted they are about as fool proof as it gets. The
Hitachi version is easier to adjust and more stable that the original
British version. The metering needles need to be matched between the two
carbs.
Either verify what is in the other one or replace both of them. You had a
mismatched piston so there is no telling what needle was in it. If they are
mismatched the car will not run right.
The Webber carbs are nice as they are infinitely adjustable with all
of the jets and such. Of course, if you don't have the jets or skill
required they are infinitely misadjustable. How many of us have seen a car
that
idles badly, has a flat midrange, but runs great at top end. The excuse being
"they are racing carbs". The Webber, Solex, Delorto carbs all have
accelerator pumps as far as I know. The SU doesn't as it fixes that problem
differently.
The answer is to use the carbs that you like and are comfortable with.
Any properly sized carb in good condition and set up properly will work
well.

Hi all,
I want to get rid of the SU type carbs. I have 3 MGs and have had many
more for 30 years. I need or shall I say my woman needs?/wants a dependable
sports car. She has a 1986 Honda Accord and a GMC 1 ton van. She keeps
getting stranded and I have to go and get the car running. By the way the car
has
a after market tube header, medium lift cam. I have been building small
block Chevys for 3 decades also. I shoe-horned a 302 ci (327 block with 283
crank) dual quad tunnel ram, 12 1/2 to 1 forged pistons, 202 heads.....you
get the picture into a 1954 Austin Healey 100-4 and a similar engine in a
1964 TR-4 both tubbed with a 9" rearend.
I need a "child proof" carb system. I am also looking for metering rods as
one is bent and the choke piston sticks. Car is very hard to start. I am
thinking since the breathing has already been updated a Weber system might
be the way to go.
Does the Weber or any other carb have an accelerator pump?
