Ok I have another question about this motor. When I was trying to start it before, I was unaware of the special qualities of a "cranking" battery, so I was using one of my deep cells. Before I replaced the spark plug it would turn the engine over for quite a while but eventually only lasted about 10 mins of trying. I then replaced the plug and grabbed the other battery, thinking either it took an extremely large amount of battery power to crank the engine and it was draining it that quick, or I had a bad battery. Well this battery stopped turning the engine over even quicker. When It would stop turning the engine over it would be nothing but a single click sound as if there just wasn't enough juice to turn the engine completely over. So I starting trying to pull start it until I eventually got it.
So now I have a brand new cranking battery. I bought the largest one they had and slow charged it at 2 amps over night. I took the boat out the next day to water test it and then tried to crank the engine using the new battery. I got nothing. Barely even a click. So I starting trying to pull start it again, and after about 5 mins I got it started again, and I ran it around the little pond I was on for about 10 mins. So whats wrong with my electric start? Is there a starter solenoid in there that could have gone out?
My next question is about all the fluids that come out of this engine when I turn it off. I know 2 cycle engines are known for being dirty and dropping oil and gas, and are banned from some lakes, but my engine seems to drop an excessive amount, at least what I would call excessive. It seemed like it dropped an unusually large amount of nasty stuff into the water when i turned it off. I'm not an environmental freak, but I try to avoid doing stuff unnecessarily, and I felt kind of bad after seeing all that stuff come out. Could there be some seals or gaskets in there that need replacing that would help this? If so, where on earth would I find them at for a 1969 engine? Anyone ever seen a place to get a maintenance guide for something this old, like a schematic break down type thing? Thanks guys.
