I'm no mechanic so can anyone replying to this speak english rather than haynes. Right my engine in my little 1.3 overruns when the ignition is turned off . . . . . . . . . . . sometimes. It doesn't happen every day or evry time i switch the car off just now and again. I've had the timing retarded so i can use unleaded fuel and wonder if this is the cause or wether it is due to the carb or something - i really dont' know. Also the engine ideles at about 1500rpm rather then 950 - 1000 as stated by haynes manual - any ideas???????
