That is a breather tube, I can't picture the motor off the top of my head but that tube is either connected to the valve cover or if the tube seems to go up over the motor then that tube goes down into the motor. If it's the one thats connected to the valve cover then it's possible there is to much oil in the valve box. If it's the one that seems to go up over the top and in then if your just alittle to much over full you'll get oil out of that tube cause that tube sits alittle above the oil level.If your oil level is right on the line then I would run it for a bit then check the oil level. If the level is still good then you should be ok but keep an eye on it if it continues to blow oil out I would take it in to get looked at futher.

You'll read a lot about making sure that the filter is clean and that the medicine cup is cleaned and that hard water can effect the operation of the nebulizer. However, the problem is most likely in the pump. Even though the pump is running, it is not pushing enough air into the medicine cup. You may even feel air coming out of the tube. When unrestricted, the air will come out, but, once restricted by the medicine cup, the air may not be fast enough to nebulize the liquid. If you want to confirm this, take the tube and hold it to the end of a bike pump, if, while pumpung, you successfully see mist, then you know for sure.
Fixing the pump is not too difficult. Over time, the chamber where the air is compressed becomes dry and, just like a dry bike pump, the air escapes from the chamber due to poor seals. The pump is pretty simple. Make sure it is unplugged from power and remove the screws holding the housing together. Inside you will see the motor, a fan, a power switch and the intake and outtake tubes. Follow the outtake tube to the pump. The junction where the tubes meet the pump is the location of the air chamber. You may need to remove the screws that secure the tubes to the chamber. Once apart, take some grease and lightly coat all of the interior surfaces of the chamber. When finished, reassemble and you're good to go!

I had the same problem! I found that the needle valve in the carb was not shutting off the fuel flow when not running. Either replace needle valve or put a shut off valve in the fule line. Should take care of the problem

Yep - that is what I would do ... find it and run something through it --- maybe blow a little air through it.
