Hi. Brand new to site. Really helpful so far. I recently bought two 96 sps. They set for a long time. I started on one by draining the gas. Changed fuel lines. Rebuilt the Carb. New plugs. It seems to be trying to hit but just wont take off. If started on Carb cleaner but wont stay running. Seems to be gettingto much oil. Plugs covered when I pull them out. Ski has original self mix still on it.
