Attempt Start and Bleed Fuel System (Initial Attempts)

What happens here

The creator attempts to start the tractor. He uses starting fluid to assist, but the engine only sputters briefly. He then explains the process of bleeding the fuel system: loosening the bleeder screw on the injection pump while cranking the engine. He observes air bubbles but no steady stream of diesel, indicating a continued issue with fuel delivery to the injectors. He mentions that these old Massey Ferguson tractors are prone to rust and algae in their tanks due to modern biodiesel.

Goal: Get the tractor running by clearing air from the fuel system.
