partner chainsaw HELP!!!!!!!

I have recently got a partner S55 from a friend that needed work. Little did i know that the partner chainsaw company has been out of business for 30 years. So, i have questions that someone on here should know.
1. Where can I get a sprocket and recoil spring?
2. What size fuel line does it take?
3. What size sprocket does it take?
4. Is there a company that bought partner out and is making similar parts?
To the people that answer this... They deserve a cookie.

Take it to a saw shop. My boss got a freebie McCollouch or whatever and the sprocket disconnected from the clutch cup. Like twisted off. So he took the cup into a saw shop and got an Oregon part matched up. Oregon makes a lot of universal parts so chances are they can cross reference one to fit yours.

thanks doug! now i have to get some money for a shop to look at it but its worth it... i hope.

When we got his matched it didnt cost anything. Although we immediately ordered when we found it.
