Had this issue on my old yerfdog. It's oil. It comes from the breather tube. Make sure it's not cracked.
What do you mean?? It's not crack or anything it just start spilling oil when it's very hot

what kinda motor? Do you have all the sheet metal parts on the motor? they help direct the flow of air from the flywheel fan. typically.
I have a techumseh ohh60

But what did the engine come of off? If its a snow blower engine you are going to have one hell of time keeping it cool. Also, I do not understand the part, it looks like it hot. Have you actually checked the temp. on that engine? As for the black stuff that looks like oil (is/is it not), your breather is not working right and your over pressurizing the crankcase.

no don't do that i'm joking. Do you have the cooling shroud on it?

Pee on it, LOL!
Seriously, very likely the breather is clogged = oil out the carb, and you need to pull the blower cover and maybe some other tin off and clean out the cooling fins, etc.
Sounds like your basic dirty engine...

Sorry- I am calling "BS" on this one!!! I have a lot- and I do mean a LOT of snowblower engines pass through my hands. There's one on my Alley Kat right now*. I ran the he// out of this engine in 100+* heat with ZERO cooling issues, as I have done in the past with other engines (many of snowblower origin).
Do you all know what makes an industrial engine a snowblower engine? Not much. Sometimes a box around the carb to help keep it from icing up, and to aid in the fact that they tend NOT to use air filters. They sometimes have a special D-shaped recoil handle to make pull-starting with gloves on easier. Sometimes a shield over the top part of the recoil to keep ice out. Often a primer bulb in addition to the choke- or other cold start enrichment device.
None of this has anything to do with the cooling system, and I openly defy anyone to prove otherwise.
Sorry. This is Canada, home of the snowblower. IF your cooling system is operating properly, it don't matter WHAT the engine came from.
*My Alley Kat is powered by an early '80's Tecumseh H60. All factory shrouding is intact, as are all cooling fins. Cold-start enriching primer has been removed. The governor is gone, I'm overgeared, and have a heavy foot... I PUNISH that thing. Oil is not-particularly-expensive SAE 10w30 per factory spec, spark plug is factory spec, and I maintain my junk.
I just did a oil change the oil was dirt as hell !!!
I also have a techumseh but its a hs40

While you're in there, make sure the crankcase is not overfilled. Take off all the shrouding and clean off all cooling fins, including those cast into the block and head, and the fan itself.
You DID use the right oil, right? Good stoich A/F mixture?

Holy ship... Calculating stoich on a friggin industrial engine? This ain't NASCAR man.

Who said anything about calculations? Read the dang plug, it's BASIC, man!
What do you mean by that?

Which part? There's lots there. Quote the part, and I will explain.

What does that mean??

All the sheetmetal on your engine- recoil and blower housings, and an other. Take it all off. You will see cooling fins all over the engine. Clean them. Clean the fan blades on the flywheel. All this together forms your cooling system!
Can you show me picture of the parts you're talking about????

Sheet metal. Tin. The metal work that the pullstart is bolted to, and all parts connected. The PAINTED stuff!
EDIT- The engine itself is aluminum. The stuff I'm talking about is steel. If a magnet sticks to it, take it off!
