Shouldn't be any, if all is good, oil at correct level. My YM2000B has none. Never noticed if it blows air out. Easiest to check is plugged exhaust.
YM2210 Vent Tube?

I ran my YM240 (essentially the same engine) this afternoon then thought to look at that vent for you. It is dry.
But the old pre-smog cars I owned years ago were always moist there. I think this can be blowby, past the rings, or water vapor evaporating out of the oil as the engine warms up.

Just to make sure all is clarified, this tube does not "blow out" anything constantly, and it has only blow out a finger tip size of oil/gunky/watery substance 2 times, both times after cold starting it.
I know I said it was oil, but after inspecting its more watery, the tractor does sit outside but it always coverd with a heavy duty tarp and I have a metal can over the muffler to keep rain out.
Tractor runs great, no power loss and only smokes under a load, powershift changes with ease, no leaks on the machine. I was just curious as to why this mixture very randomly comes out the crankcase tube.
Thanks all.

after running mine this weekend for 2 eq. hours, while letting cool down idleing i checked the tube as i was down there and thought about you. The tube appears oily, yet i have never seen a drip under the tractor. I did remember putting my finger to it to feel any pressure, there was none but i did have a tiny say half to 1/3 drop that when my finer was there it came off. This was after bushhoging and bouncing on some rough areas and had tiltited to that side on a side slope so i dont know if that contributed to it? Like i said after it has been sitting on my concreate carport or onthe trailer it has no drops that fall from that point. My guess is the oily tube if from vapors or oil mist? BUt i do not usually see any thing dripping or blowing out of this tube.

Thanks clemsonfor, I have yet to see a drip of fluid under my tractor from this, no white smoke or mist coming out either. Just a smidge of oily/watery stuff left on the frame. I don't think its that serious, or at least no immediate overhaul needed. I cleaned the frame and plan to monitor it over the next few weeks.
I read that the 2 cyl is always harder to start then a 3 cyl, so that eased that worry a bit, anyway, if this thing did need an overhaul in the future what kinda price range am I looking at? just curious. I gave $2800 for the tractor and I changed the fluids, replaced the warning light panel, new air filter and changing the hydro fluid in the next few weeks.
One more question, looking at the muffler, there is black carbon buildup in it, I guess that's normal? How do I clean the muffler?

unless its cocked up (the muffler) i would not worry about it. Its just clamped to the manifold so take it off and i guess you could run water through it or deisel fuel to rinse out the inside and then blow it dry? Mufflers and pipes get sooty they have burned hydrocarbons through them go stick your finger in your trucks tail pipe and it im sure runs cleaner than a 30 year old diesel tractor

On the rebuild i have no idea the cost. That would depend on if your just buying the parts to do it your self or haveing a mecanic do it and then it would depend on his labor price and what he does to it. By tthat i mean will he jsut rering the pistons and put new bearings in it or will it need new liners or crank turned, new pistons, etc. etc.
