Hi everybody,
I am hoping someone can help me here.
I have an 850 sport coupe and I am struggling with an idle problem. I thought I had solved it a few times , but each time it comes back.
The car had been running fine, when suddenly it stalled at some lights. I could get it started easily enough but every time I stopped it would stall. After googling the problem it seemed like I had a blocked idle jet and sure enough after cleaning them out it ran well again. But a few weeks later the problem came back. This time I sprayed some carb cleaner at the base to check for an air leak and sure enough every time I sprayed it the revs would rise. So I bought a carb rebuild kit. After the rebuild it ran well (probably better than it ever has). It would even run as low as 300-400 rpm without stalling. I thought the problem was solved an it ran well for about a month. But last weekend the problem came back. Did the spray of carb cleaner test and once again the revs would rise. I tried just giving the bolts holding the carb on a slight tighten, but it didn't make any difference. So I took the carb off again to see if I could see any problems. The base seems flat. But it seems like a lot of the screws / bolts had loosened slightly. I thought maybe I just hadn't tightened them properly, but there are so many that I can't believe I would have missed so many. Would they have just vibrated loose? If so how do I stop it happening again?
Thanks for any help
Rob
