Thanks guys! Seems I have a few jobs this weekend. If I find anything useful I'll try to link a photo.

nhdoc - thanks for great support.

Munichtaxi - depending on the age of your car, I believe there might be two relays. Later cars have one carb choke controlled by a temp sensor of the block - won't fully open until the engine is warmed up. I think that was post '71 for the M180 engine in most markets, not sure about others including US which had different emission control stuff. So there must be two relays for that system.

Blue 72 250 - thanks for advice - great diagram.

I'll keep you posted. Thanks again
