If your fuel lines were perished, then most likely your carburettor diaphragms will be hardened/contaminated too.
Sounds like you will need a carburettor kit. You will need to identify what manufacturer the carburettor is
ie:
Walbro, Tillotson, etc
If Walbro (most common) you need a D10-WAT Diaphragm kit, and suggest an inlet needle and screen whilst you have it apart.
