so i have an 82 100 sport..

was driving great.. cruising around neighbourhood.. then one day.. it stalls while driving and won't restart. so i pushed it home

next day.. when cold.. it starts first or second kick.. runs for 5-10 seconds then dies - won't restart

has been consistently like this for a few days..

any ideas what it could be? Gas tank was resealed so i don't think its rust from there..?

should I clean carb? what else can I check?
