If the fuel level in the tank is/was higher than the manifold intake ports in the head, and air cleaner hose connections were good & tight, like any other liquid it will seek its own level. That also means the air cleaner is also full of gas up to the level of the intake ports where the manifold attaches to the head.Just bought the tractor and it is puking oil, waiting on compression test that will be here Wednesday to check compression. I understand when the needle in a carb sticks and floods gas but not on an updraft carb. Just curious if anyone else has run in to this issue?
Yep. DJ has it. The updraft carb can be lower than the engine, but if the fuel tank is above the engine, then that's how the fuel gets up into the intake manifold. It's not where the updraft carb is, it's where the fuel tank is. All it takes for that to happen is a stuck float bowl needle and a plugged carb vent....both very common problems.If the fuel level in the tank is/was higher than the manifold intake ports in the head, and air cleaner hose connections were good & tight, like any other liquid it will seek its own level.

Kit the carb. change oil, dry out the system.
