I bought a trashed D reg 1.3 SR for spares or repair. Just cleaned by Pierburg 1B carb on my 1.2 and decided to put the 1.3 on instead. The haynes manual says that the 1.3 should have a pierburg 2E carb on.
However my 1.3 has a weber carb. Cant find exactly what model it is, it says 3554 on it a couple of places.
I presume it was updated to auto choke?
Can someone help me identiy this carb?
