After running engine with muffs on trailer oil/fuel mix coming out exhaust anyone no what this could be? Leaves a small puddle on ground under drive kinda black oily smells like fuel/oil mix.vro pump is about 10 yrs. old. Check compression checks ok, spark was very weak to all cylinders so I replaced complete ignition system, stator, power pack, four coil, and a regulator. Had all original parts so I replaced them all now it seems to idle about 1200 rpm with muffs kinda high. I also removed carbs, checked float level and cleaned, needle and seat operation good. Did all set ups except max advance. Idles ok typical 2 cycle. Need to water test. I thought that because of the weak spark it might have been excessive unburned fuel, but it still leaks from exhaust, going crazy here :? Any input would be greatly appreciated. I am a guy guy on the block. Thanks :)

Sounds like unburned fuel it could be just fine
