1973 Poineer Chainsaw 1073 spraying chain oil

Hello everyone, I'm new to the forum.
I was given an old 1973 Poineer Chainsaw 1074. It was not running and the inside was solid with sawdust.
I completely striped it down and cleaned it. Carb off and soaked over night in carb cleaner then used air to blow it all out. Completely cleaned motor and all interior parts of any sawdust. This was caused by chain oil leaking and caking the sawdust everywhere inside and outside the chainsaw.
After completing the cleaning on the chainsaw and renewing the spark plug and air filter it took 5 pulls and it started, but chain oil was still spraying everywhere.
Could someone help as I feel this was probably the reason for the chainsaw to pack up working in the first place. Is there too much chain oil in the oil container or is it something else??
Please someone help....

 

I'd be thinking the hose came off the orifice that meters it to the bar. I'm not familiar with that saw, so if the oiler doesn't use a hose, I'd still be looking at whatever passage it goes through to the bar and see if something has popped off or been drilled out.
