Hi, I have an early sport where the carb attaches to the cylinder head via a short threaded alloy tube. The challenge I have is the threaded tube has lost its thread, and consequently the carb has fallen off!

What can I do?
Options appear to be
a) get a new tube from NLM (will call them tomorrow, but my hopes aren't high)
b) get a secondhand one that's excellent condition ?????
c) get the existing tube some alloy welded to it an cut a new thread? (anyone have the skills to do this?)
d) use a hermetite type sealant to build the thread and 'glue' it in?
e) change this carb (or both) to the later set up of rubber connectors? (was this why the changed the set-up)?

Any advice or parts for sale apprecciated

The solid alloy inlet manifolds are not well thought of. They transmit quite a lot of vibration to the carbs causing wear and running problems. Square slide Dellortos wear out fast enough as it is!

NLM sell conversion stubs to use the later rubber manifolds, which is really what Morini themselves did.

I've probably got some spare eary manifolds if you really want one.

I'd certainly like one if you have a spare, perhaps you could call me?

I'm intrigued as to how the rubber attachments support the carbs when K&Ns are fitted (as they take away the suspension provided by the standard air intake box).

Easy, they don't, but it's usually been found that they run much better with the air box. With one carb facing forward and one backwards, how whould you expect them to see the same air pressure?
