Welcome Rob A:
Chain saw lines are typically clear plastic tube which you can buy at Lowe's. I would connect one end to the gas tank or resivoir clamp a filter in the line if there is one there and stick it on the side of the carburetor (that's where the choke is and where the chainsaw floods and runs out)
If you can find those connections, hook it up and give it the ol' smoke test. Prime the carb, turn the ignition on, close the choke, and pull the rope. If it smokes you have the correct connection but maybe a little too much oil in the gas.
