Well guys, my uncle dropped off a 1979-1980 KDX yesterday, I think it's a 400. It leaks gas out of the carb vent lines like crazy, I took the carb out, it was filled with varnish, ect. After a good cleaning it still leaks. It must need a carb rebuild kit, where can I get parts for this? It doesn't give any spark either. The kill switch is missing. Other than the fact that all the plastic is craked and faded it looks ok. What kind of fluid goes in the clutch? Also do any of you know the original fuel oil ratio? How do you tell the engine size? The VIN says 400 in the begining. Thanks for any help!
