Hi all
Recently bought an old mk3 cav with 1.6 carb (16SV engine) as a winter hack as it was going cheap and had lots of MOT.
I am however slightly puzzled by the idle speed. It will remain high for some time even after the choke has gone off. I can see this because the choke plate is fully open. It eventually drops to normal, but if I stop the engine and restart it a few minutes later it will sometimes go high again for a minute or so. Blipping the throttle has no effect.
Upon inspection, I see that there is a wire going to the choke housing, and another goes to some sort of solenoid valve on the left (as per car) side of the carb. What do these wires do? It's a pierburg carb I think.
Any ideas anyone?
I didn't want to go ripping the carb apart with no idea of the cause, given how sweet it otherwise runs.
cheers
