I just bought a 1975 Montgomery Ward tri-hull, bowrider, with a 55hp 2cyl, 2 stroke, Sea King outboard, it turns over, got spark, and 50:1 fuel. but wont start, there is no air cleaner, (i need one?) alittle drops of gas, leak out where the air cleaner should screw on, am i getting too much gas?? where are adjustments? and how do i adjust them? Thanks for your advice, Im new here, Rick
