my square has been running rich of late and then it lost all compression and would stall when ever i didnt accelerate so i pulled it apart and of coarse it was as simple as the hoses on the carbies. however i opened my airbox and it is filled with oil. now im stressing that it could be the head? when i say filled its more like a quater full is his normal?

Um, if it's an oil bath air cleaner then it definitely is normal. They require oil in them to filter and have a required oil fill level marked 'Olstand'. What kind of 'airbox' do you have?

If you lost compression then you are dealing with more than carbs
