we have an old "bomber", late 70's.  had it working okay up til this winter.  it won't stay running anymore unless gas is poured into the carb...it won't suck gas on it's own.  Why?

 

[Rocketman]

air leak somewhere?

 

[Mr Siv]

is their junk over the screne in the gas tank? try replacing all the hoses. if theirs a fuel filter replace that.  
good luck,

What kind of carb is on it.  Is that a diaphram carb?

 

[mike800z]

if it has a tillitston carb it might need a complete diaphram rebuild kit
