My Apollo has the 350. It’s my first Buick 350. Had many many sbc but first Buick. It’s all original and stock. It’s the 2 barrel carb. It runs like a dream at idle and when cold. The problem is when it’s warmed up or hot like in traffic it dies and is hard to get started. You have to crank it and pump the gas like a mad man. It acts like it’s out of fuel but it’s not. Then when it goes it misses and barely runs. If it’s cools for a few mins it runs fine but then a few miles down the road it does it all over again. I have heard lots of things. It’s the gas boiling in the carb. It’s the ethanol. It’s the fuel pump. It’s the coil. But rather then throwing money at everything I’m sure someone on here has the problem. Thanks in advance.
