Hi All,
I've recently purchased a 1980 bluefin w/ a 1980 70 hp johnson outboard. The motor runs like a top however it seems to load up when running at an idle, it will only start loading up after it has been idling for a while (when I troll with it). It also has a lot of hesitation when throttling up and it will sometimes die when throttled up to quickly, if i throttle it up slowly the motor will catch up and run like a champion. I assume that it is a carburetor issue however I'm not familiar with this type of outboard engine as there aren't any jet adjustment screws, I assume that this motor has fixed jets? If you guys can steer me in the right direction it would be greatly appreciated, thank you.
