I have an engine that was running perfectly three months ago. I crashed the plane it was in and the plane and engine has been sitting for those three months. I repaired the plane and tried to start the engine, but it is so rich it will not start. The needles have not been moved, but fuel gushes up through the carb and spews out all over the place. It looks like Old Faithful. This is an OS .46LA which has an air bleed carb, but it was running beautifully before the crash. Anyone have any ideas? I'm at a loss.
