Have an 86 50hp Mariner, 3 cyl, 2 carbs. Motor would start, idle fine but bog down when trying to accelerate. Got carbs rebuilt 1 year ago.<br /><br />Shop said carbs needed to be rebuilt again. Just couldn't part with the $$ so I thought I would try myself - experience is nill. Got the carbs out and soaked all parts in carb cleaner (B-12). Put back together and tried runner motor with ears on motor.<br /><br />Symptoms: Engine is running rough (missing) and white smoke coming out. Gas leaking from carbs Won't idle without stalling unless I give it gas. (It was idling fine before I pulled carbs)<br /><br />I ordered a manuel but not in yet.<br /><br />Questions:<br />1. The only screw on the carbs I see to adjust is needle screw (that has the spring on it). I assume this is idle screw. How is this adjusted - 1 1/2 turns out?<br />2. I keep hearing talk of adjusting the floats. What is this about?<br />3. How important is it to get carb kit and rebuild if all parts were cleaned thoroughly and looked clean?<br />4. Is it ok to run motor at high rpm with ears on motor? If so, should I expect to be able to get motor rev'd up just like in the water?<br /><br />Anything would help.
