Ok. Here are a few pictures of what is happening:<br /> http://204.26.80.53:8080/boat/motor.jpg <br /><br />closeup is:<br /> http://204.26.80.53:8080/boat/closeup.jpg <br /><br />I did some testing in the driveway, and figured out what is happening. Now<br />I need to figure out why.<br /><br />After running the engine for about 15 minutes.. stopping... then running<br />about 15 again. stopping.. then running again, the small oil tank on the<br />engine began to over fill. Usually, the oil is up to the top line that is<br />on the side of the reservoir. On the third run of the engine, it started to<br />fill, until oil was coming out of the small vent hole on the top right side.<br />Oil also started to come out of the air intake by the carbs (See the Red<br />towel on the picture, this was catching the oil as it dripped out).<br /><br />I took out the float switch from the oil reservoir, and took it apart to<br />clean it. When I inserted it back into the reservoir (which was COMPLETELY<br />full of oil.. I could see the float floating to the top. I have to assume<br />this float switch is not working for some reason and causing the engine to<br />continue to pump oil even though it is full.<br /><br />what do you think? Anyone ever have this go bad, and how much do you think<br />it costs to replace?<br /><br />Second, since I know the engine is getting enough (too much oil), is there a<br />way to bypass this switch so I can at least run the engine. Knowing its<br />about a 50:1 ratio, I could burn a tank of gas on the oil in the reservoir<br />and not have any problems. I really want to run this on the 4th, but can't<br />get in to the shop until next week.<br /><br />If someone thinks it is the switch.. I may be able to get one tomorrow and<br />replace it myself.<br /><br />Thanks for any help!<br /><br />Now here is a stupid question. Is this little reservoir considered the<br />"Main Tank" or is it the "reserve"?
