If you take the dipstick out while the engine is running it will for sure blow out air and oil. It's basically a sealed system designed to keep air out. When you take out the dipstick you open up the system sucking in a lot of air when the piston goes up the bore. When the piston comes back down the bore that air has to go somewhere and it comes right back out the dipstick tube. Perfectly normal. As far as running hot. Look at how the spark plugs are burning. Do they look normal or are they grey/white and ashy looking? If they look normal and there is nothing blocking the intake air such as built up grass and debris then it isn't running hot in my opinion.
 
Bought a 12" dial thermometer.(forchecking deep fry oil) Checked oil temp right after shutdown. 225 degrees. Looks like I'm good to go.
During the summer months oil temp between 275 and 300 is not unheard of. Anything below 320 isn't a concern.
