<p>I managed to get a picture of my 72B setup (engine/carbs from a
71BGT) that shows some relevant connections, that I have attached.<br>
</p>
<p>Now on the original picture, I noticed a number of issues which I
will describe, starting from the engine and working out.</p>
<p>The intake manifold where you have looped in two ports - the rear
port should have a nipple to connect a vacuum tube to the
distributor. Other port should be blocked using a fastener.</p>
<p>On the engine side of the carbs, each carb should have a port
(5/16") to pull in crankcase gasses. This uses rubber tubing and a
plastic-Y piece to then connect to the crankcase side cover. Moss
shows this here:</p>

</p>
<p>The front linkage for the choke - your picture shows it near the
rear carb, should be moved towards the front carb. That is because
the choke cable will connect to Moss 372-340 bracket so that brass
lever needs to be close to the bracket.<br>
</p>
<p>And finally, the float bowl covers - they are reversed in your
picture. The three port cover is for the front carb. That is
because the 70-71 Bs had a steel fuel line running towards the
front of the car and the fuel line ran off of it. Then you have
another port to run a fuel line between the two carbs. The
overflow port should point out away from the engine/carb. The
70-71B would run lines from these two overflows back to a charcoal
canister. Since you are using the engine/carbs in a MGA, you could
use the earlier piping method used on the 62-67 MGB. These are
steel tubing bent downwards so that the tubes divert petrol
overflows to the ground. There is a bracket that holds them to the
engine block, available from Moss.<br>
</p>
<p>Steel tuning is part 67 -

<p>No longer available but you can make your own which is what I did
on my 64B.<br>
</p>
<p>I am not sure where the MGA fuel line would be to connect to the
SU carb. If it is not practical to use the 71-72 method of fuel
routing, you could use the 62-67 method, replacing the two port
float cover with a 2 port and use a T fitting on the fuel line:</p>

<p>Hope this helps. <br>

These carbs are on an mgb engine in an mga. We acquired this
project in kit form so I'm not sure what i have.
