I am stumped. ~ 84-85 Mercury Classic 50. I let my boat sit for a few months without winterizing it...strike one. I drained the old fuel, bought new and mixed 50:1. Removed carbs, cleaned them and realized bottom carb had a stuck needle. Reinstalled both carbs and replaced all fuel line. Bought four new plugs and getting really good fire. Now my problem, I'm getting fuel, spark, but no start. I have tried everything I know to do. It ran like an absolute champ last year, but this year, nothing. What could I have done wrong? I removed the starter, could I have criss crossed wires somewhere without knowing? The starter gear now stays connected to the flywheel, I don't remember it doing this in the past.....please help.
