4 HP Briggs Lawnmower smoke smells like burning rubber

It smokes while it is running but after you shut it off the smoke come out the top of the engine and it smells like burning rubber. I have no idea what it could be.

I have had funny smells when burning fuel that has had a fuel stabilizer added.

Have you checked to make sure the oil is to the proper level? The only thing rubber inside the engine I can think of would be the seal where the shaft protrudes from the case. Without oil the friction might burn the rubber.

Check the cooling fins and make sure to look under the shroud. The fan may have sucked something in and is burning on the cooling fins.

Thanks, it is full of oil maybe the oil is not getting to the seal some how? Is that possible? The rest of is looks clean.
