For those of you who have not been following my problem, here is a short description:<br /><br />1966 Mercury(merc 650) 65hp 4cyl. Been on lake 3 times. Engine died at full throttle in midle of lake. Ran hard all day(3rd time out), then slowly started to lose speed. <br /><br />I was reading my manual and i came across something called vaper lock. So I performed a prodedure they described. It involved removing plugs, grounding leads, cranking 10 times, cleaning plugs and returning them. Then trying to start.<br /><br />It would not start after that. Then I had someone try to start it and I used a screwdriver to push on a lever that opens the flap in the carbs. It fired up and was running great with the warm up lever all the way up. I lowered the warm up lever and it ran for a few seconds then started to sputter. I lowered it all the way and then it stoped. I tried to start it after that and it would not start again. I did notice white smoke coming out of the bottom carb.<br /><br />I have concluded that there is something wrong with the regulation of the air and fuel. Please let me know if I am completely wrong, or what I need to do. Thanks.
