<HTML>I have a 1980 Motobecane, ( doesn't appear to have any other name). I HAD it running rather well at one point, but after I replaced the fuel valve it has never worked right since. The engine won't turn over unless i turn ON the kill switch, then to start it up i have to go down a terribly steep hill, pedal like MAD, and turn the kill switch on. Once I hear the engine start to sputter, i turn the kill switch off. This went on (it got harder and harder to start) for about a month, then i put it in the garage for around 1 month. it won't start up at all now, and is leaking gas from somplace (i can't find out where). How would some one go about doing an entire rehaul on this engine? The Frame and wheels and brakes are in good condision and work great. Any ideas?</HTML>
