I have a 1998 Johnson 50hp two stroke. I have an electric starter with the push in key choke. When ever I go to try and start my engine, it turns over normal and then cuts off like it's not receiving fuel. I always move my idle level all the way up as soon as the engine turns over and it slowly dies out. If my engine doesn't cut out, eventually it warms up enough to start idling higher. I'm not sure if maybe my idle has wiggled itself loose and isn't idling high enough? I'm not sure if maybe I need a new primer ball? I eventually can get it started, but something isn't right here. My rpm gauge shows im idling at 2000rpm when I'm at high idle and about 900 when im at low idle. I pulled my spark plug connectors off one at a time to see if maybe it's a carb problem. When I unplugged the top one, my engine continued to run fine on the ear muffs. When I unplugged the bottom one, my engine cut off after about 10 seconds? Could this be a carb problem? Or is this two separate issues? Any thoughts please comment.
