ok i got this motor for free. i cleaned the carb and replaced the fuel line. it started and ran a month ago. then i rebuilt the lower unit on it. put everything back together and it wont start. it acts like its going to, but it just wont. i know its getting good fire and the spark plug is good...
after i started and ran the engin for about 5 minutes in a bucket of water i see spots of brown looking oil floating on the top of the water. what should i do? and what could the oil be coming from?
