I must have something else wrong then as that one doesn't have the right angles

This ad seems to be pretty much what my sets look like - hope it helps? I see the two spring extensions in your box of bits.

Those ebay carb's they appear to have an odd set of pistons one appears to have been flowed and the other is standard.

Are these the correct float bowls for the carb tags listed. Finally pulled everything out of the cleaner and can now read the part numbers on the castings.

Nick. I believe the correct number is AUC4814 and they would use 2 of the RH floats for the LHD setup. The other float is AUD4815 & also 30deg.

[NicholasUpton]

I assume they are correct, no AUC but cast with 4814

Yup, those are them. You can see they're 30deg and not the more common 20deg ones. The omission of the "AUC" may be reproduction ones?. (Burlen sell some), but I'm not 100% sure. I'm sure someone else here can confirm that..

They are original SU bowls not burlen ones .

The most difficult item to find to build up a set of H4,s with 30 degree bowels

My 4814 is cast with the number only and no “AUC”

But the 4815 is cast with AUC
