I have a 241 that is not run in three years I know of. Anyway I cleaned the carb, changed the oil and after a bit of tinkering it starts right up. The throttle shaft is worn as it idles fast so I put a small spring on for now and will get to that later. Question is I notice when I first start her, there is blue smoke, quite a bit at first but it clears up after a bit. Any opinions? Valves mabe or stuck ring? Can't be real serious as it runs perfect, or close to it for being 42 years old.
