Reading previous Posts tells me that high engine idling speed is a somewhat common problem, but no-one seems to be able to supply any answers to it. My Sportrak was fine until it went in for the dreaded MOT, and now it idles at around 2500rpm. The tester swears he adjusted nothing, yet something has obviously changed!! I do have some mechanical knowledge, but the (over?) complicated vacuum system associated with the carb has got me beat! I can reduce the idling to near normal by adjusting the screw that is beneath the throttle mechanism, and is only visible when the throttle is held wide open, but this results in bad starting from hot. The engine will only start if the throttle is held on full whilst the engine is being cranked, and stalls if the revs are not kept high for about 15 seconds or so. Cold starting is as normal. Any clues/advice/hints etc would be most welcome - it's a pig to drive as it is - nothing like its normal self!!
