I had a problem similar to what you describe in my '80 Westy. Ran fine when cold, then faster (up to 4000 rpm) when warm. Had a mechanic look at it and he found that when we disconnected the D-valve (part of the vacuum system), the idle remained low. Wish I could tell you more about it but since I punted on this one that's all i know. Oh, the D-valve is located at the front, passenger side of the engine compartment, looking down on the engine from the hatch.
