Hello I have already written here several times some will probably remember it was about FC 31 and 94 that the box runs only on 3 cylinders sometimes….. I changed the KWS and today I also installed the new distributor had the presumption that the Hallsensor was defective….. yes everything went together and after 2-3 km nothing ran only on 3 cylinders takes no gas on had to play a lot with the clutch so I still got home now but found every time I pull down the candle plug from 1 cylinder there is an overpressure and hissed that I have had now 3 times of course the candles exchanged over and over again on the 1 pot now is my presumption that in the cylinder head what is not right maybe a crack ???? have really no more buck on the box has cost me now so much money and now bring in the workshop and that surely also long and expensive fangs ???? has one of you an idea od he would have had such a thing before would have been very grateful about your help mfg Stefan
