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?

air leak somewhere? http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/confused.gif

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?

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