Hello everybody...So this is how it goes...I recently bought an 87 Camaro and was told there was old gas in the tank so Every two days without driving the vehicle I would go outside and start the engine and let the car run for ten minutes...Im not to familiar with cars and wanted to get into knowing more about them...So heres the problem..Yesterday Morning I started my car once again and let it run for ten minutes while it was running i went in the house to watch some Tv and then I heard a loud popping noise..so Im thinking to myself god I hope that isnt my car..It sure was..It was smoking very bad ..So after the smoke was gone I wanted to somewhat determine what the problem was knowing nothing about cars..Well a little... So from what I have seen there is greenish yellow liquid Coming from a Canister that on the top says Rochester Carb Tank that has two hoses on them...One leading to the carburetor and the other unknown... Could somebody explain this to me and from your perspective what the problem could be
