MG MGA - MGA/Magnette carburetters

Are the SU carburetters used on the ZA Magnette identical to those on the MGA 1500/1600?

The same SU H2 carburettors but they specify different needles.

From memory standard needles for MGA 1500 are GS and for the Magnette EQ. I can't remember the MGA 1600 and MGA 1600 Mk 2 needles.

Also different rich and lean needles.

I suspect that the difference is marginal at best (FWIW my MGA had EQ fitted but was more responsive when I got GSs

ZA had H2 = 1 1/4" carbs
ZB had H4 = 1 1/2"
MKIII & IV had HD4

MGA H4 are substantially the same as the ZB. Differences are jet needles and some linkage bits.

Thanks. I have access to a pair of ZA carburetters in good condition that I could use on my MGA coupe project, but thought they looked a little smaller than those that came with the car. And they obviuosly are!

Just wonder: As we know, when the MGA was introduced it had 68 bhp, but this was soon increased to 72. Could it be that the very early MGAs had the smaller H2 carburetters?

I think the change came with the engine no change from 15GB to 15GD where they changed a variety of things.

There's no record of the smaller carbs being used on an MGA (I got my H2s and H4s confused earlier)
