I just purchased first boat, it has a 1970 Mercury Thunderbolt 65 hp on it. It takes 5 to 10 key turns to start it and ran ok if not a bit rough and then just stalled. Pumped fuel bulb cranked a few times and would restate for a bit and then die. Seems to run a bit linger on full throttle vs low speed. Low speed engine dies pretty quick. When engine does restart you can see a bit of gas floating on the water.
With cover off, the carbs look damp at the air intake - it has two carbs joined by plastic rod.
Could it be dirty carbs - if yes how to clean and when people say turn the screw to adjust mixture, which screw?
The carb on top has a plastic piece that looks adjustable to the throttle, the plastic link rod has adjustment between the two carbs and then there's a screw to adjust air to fuel ratio?
Does anyone know what to do to set etc
How to check spark plug for lean vs not mix etc
How to check have power to each spark plug etc
Thanks
