Been rebuilt with new weber kit and everything cleaned including all jets etc.

Its funny its working one muinute and not the next. Has it had new HT leads put on it recently?
Brand new everything pretty much. New leads and plugs. Just been out for another run, starts ok pulls away fine at low speed and high speed, a few roundabouts with alittle gas and straight line speed which was all fine.
Not counting my chickens yet. Got football early tomorrow which isn't a long drive so see what it's like in the colder weather with a cold engine.
Carb icing sounds favourite as Baxter said!
Try putting a warm air pipe from the exhaust manifold to air filter and see what that does!
If your running with a K&N filter that could be the issue - alternatively put on the standard air box, I have the adapter somewhere for one I think!
Just another think - check the brake servo vacuum pipe at idle. Move it around whilst its idling and see if anything changes.
What RPM does it warm idle at?
Iv got it idling between 1000-1500rpm. I'm using a ramair foam filter rather than K&N. I don't have the original sr filter as the pierburg had a K&N on that. Manifold is a 4 branch.
Iv not connected the oil breather to the filter, it has a seperater breather filter on the end of the pipe. Poss warm are coming from that but as it blows alittle smoke I didn't want to connect it back to the carb.
Edit:
Still don't think it's cold enough for carb freezing at the mo.
It doesnt need to be that cold. Its to do with the Joule Thompson effect. When the fuel is forced through a small hole it atomises and expands creating a cooling effect. its the same as when you spray deoderant on it feels cold as it changes from a liquid in the can, to a gaseos vapour in the air.
definitely get the standard air box on it in the winter.
what you got to remember is,
5 or 6 degrees air temp is low enough to cause carb to freeze,
fans blow cold, when its hot, this is whats going on in your carb on a massive scale, as its sucking cold air, it makes it even colder, enough for the fuel vapor to freeze
Ok I see always assumed it was when its very cold that carb icing accured. Would linking my breather to the air filter help? I didn't originally do because i wanted to reduce emissions for mot purposes but if warm air comes from that then that may help issues.
