Hi All. I have an 83 Cargostar 1610B w a 345 that Im just getting running after sitting 10 years full of gas. I cleaned the carb really well and made a new gasket and it started and ran instantly and totally purred!! however shortly after there was gas leaking out of a hole on the bottom where I assume its some sort of vent for the main jet. When I took it back off and blew air in the hole it came blasting out the hole for the main jet. Any ideas? Im working on pix.
