Hello everyone! I have a 1977 c3 with a 350 engine in it this thing runs. Eautiful but for some reason it died on me yesterday while driving and it seemed like I ran out of gas which I wasn't, I pulled over and car wouldn't start it kept cranking and turning but it slammed like I wasn't getting gas so I pored some gas in the carburator and I keep the gas pedal on the floor and now rims again, can anyone help me determine what happened or what should I be expecting ?
Thank you
John

Welcome to the forum John. Well it's gonna be a process of elimination. It sounds like the carb is getting gas so the fuel pump & filter should be OK. The float could be sticking on the carb or the needle could be sticking which would not allow gas to fill the bowl. I would recommend having the carb rebuilt by a good carb person it's time anyway being that it's almost 40 yrs old.

Thank you Alan for the quick reply ever since this happened my headlights don't go down anymore could that possibly have a vacuum Line connected to the carburetor?
I heard of a brand called quick fuel carburetor 750 CFM I found one here local for $340 and I was thinking to buy it and install  that what's your suggestion?
Thank you
John

Yes you could have a vac line disconnected, but it should start just not idle right. A 750 is to big for a stock 350. A 650 Edelbrock is a great carb for good all around driving. There's formulas on the internet to figure out carb size, but 600 to 650  is where you need to be. The stock carb is great all it needs to be is rebuilt ...cheaper & it matches the car exactly.
