So what does white smoke mean coming from a crankcase vent? The 107 (K241) finally freed up its oil control ring, and she stopped burning oil. However, it started blowing white smoke from the crankcase breather.

Tractor is not running lean (in fact it's actually running a bit rich, I should probably tune that better) and there is no debris beneath the fan shroud, so I do not believe it is because of overheating. The machine also blows a bit of white smoke out the muffler upon startup, but clears up once it warms up. It runs fine, throttles up and down no issue, no sign of it bogging down like it's overheating at all, no engine knocks (other than the worn drive hub that I need to replace). I gave it an oil change after I got it running 3 months ago, hasn't been used much since then, oil is clean.

Might there be something in the oil trying to boil off? Maybe some condensation from the engine walls? (it is, after all, cast iron). Maybe there's a little bit of gasoline that somehow managed to leak into it during the short time that it didn't have a shutoff valve? Carb is new so I wouldn't expect a bad needle and seat, but you never know.

I am thinking that the white smoke from the muffler is because of the rich mixture, but I am completely clueless about the crankcase vent. Anyone know what the issue is here???
