It is the built in Victa failure feature responsible for the destruction of countless numbers of Victas because of this dumb assed feature that was dreampt up over too many long lunches at the pub by the design engineers.Ho any sane person could come up with that idiotic design beggars belief. I hope you understand I now feel better. Three things cause the cable to jamb, one is the kill switch rubber and the other is the insane hump on the cam, that is real nutty territory. The third is that you have bent the cable when you have been fitting it back into the carby housing
