engine loads up with oil

[steplift20]

thanks for all the advice, the only thing that has me confused is that i own the engine for about 18 years and only recently i am having this problem and i do the same thing all the time i all ways topped off the oil tank during off season, i think im just going to get rid of the system and premix, i also have a 50 merc that is premixed and she never gave us a problem , and you know when i will have the problem, when im getting ready to go out and she doesnt start, probably have my wife with me and she doesnt come often she will think i had this all planned
