My mk2 golf 1.6 suffers from carb icing in the winter resulting in having to stop every 10 miles or so for it to de-ice. Its reportedly a common problem with the model because of the carb used, and the best fix is to replace it for a weber item.

However, this car only has to last me another week and isnt worth spending the money on for a replacement carb. With this in mind are there any bodge fixes which might make journeys a little easier? frustrating having it cut out all the time.

All warm air hoses / air cleaner assembly are in place and set to correct winter settings.

Could you explain how that will sort it? The problem is with the incoming air temp rather than the engine not being up to temp.

The other option - hose is in place and air cleaner set to winter

Thanks for the explanation + advice.

The engine is an old non crossflow thing. The air is drawn into the engine bay via a ducting near the front grille, via a junction where hot air is mixed in (ducted from a heat shield over the exhaust manifold), then over the top of the engine to the car which sits atop the inlet manifold, which in turn sits over the exhaust manifold.

The original design calls for the carb to be electrically heated, and this aided by a coolant fed automatic choke is intended to keep it all working, but over time the auto choke gets gummed up with crud and the electrical circuit stops working.

I'll try rerouting the air intake to behind the radiator and if that doesnt help block off part of the radiator.
