T could be one of a few things.

It could be overfull.

The baffle could be missing/fallen off

excessive blowby, ie. bad rings

Thats about all I can think of right now

Might be your baffle.

What oil are you using?

Theres a little thing behind where the tube connects called the breather housing. Its to keep oil from splashing into the tube.

Check to see if the oil smells like gasoline - if it does, change the oil FIRST, then either rebuild or super clean the carb - usually if the oil is over filled, its due to gasoline leaking into the oil ( thru the valves) because the float bowl sticks and lets gas flow even when its off. If the tractor is run with thinned oil, itll melt the berings and blow the motor.

Id also suggest a fuel line shut off valve.
