I recently bought a 1997 900SS and am reviving it after 7 years of sitting in a garage. I have replaced the battery, Changed the oil, replaced the fluid in the brakes and gave it a quick once over. The Clutch is flat...does nothing when you squeeze the handle. I tried to change the fluid and bleed it but still nothing. I decided to fire it up after draining all the fuel and filling it with new fuel. It will fire for a couple seconds with the choke on fully but will not stay running. Where do I start? How tough is it to rebuild the carbs? Could the brake master cylinder have went bad from sitting? Any input would be appreciated. Thanks, Rick.
