Zenith 26VA differences

[Ian Wegg]

I'm sure I've seen this covered before but a search of the forum didn't turn it up for me, so apologies if it has.

I've recently managed to get a refurbished Zenith 26VA carb and I've realised the float bowl on the one I did have is different. In particular it is heavier and has a completely flat base. It also has "Z3" stamped on it.

I'm assuming this isn't correct for a 1933 A7?  It has been on the car since I bought it a year ago and has been working, although the mixture has always been too rich. The attachment bolts are hexagonal rather than square, if that's a clue.

Thanks for any help and once again apologies if this is a rookie question!

I had a parallel problem when I first had my car, and posted a question on this forum. Ruairidh Dunford was especially helpful in getting the right bits with the right carb (they are not interchangeable).

If you look for this thread, it is called "Carburettor Problems" and is on page 228 of the forum

Thanks David, I knew I had seen it here before.

I'm off out to the garage again to check.
