Initial Engine Start Attempts and Fuel System Verification

What happens here

With the new battery installed and fluids topped up, the host attempts to start the engine by cranking. When it fails to start, he tries using starting fluid sprayed directly into the carburetor. The engine sputters briefly but does not run continuously, confirming that the ignition system is functional but there's a definite fuel delivery problem within the carburetor, necessitating a rebuild.

Goal: Confirm engine's ability to fire and definitively identify the carburetor as the source of the fuel problem
