Can a bad carburetor cause an engine not to start?
If the carburetor has any sort of issue that disturbs the air fuel ratio it may result in hard starting. Depending on the exact nature of the issue, the vehicle may be hard to start, and get better as the engine warms up, or it may also be difficult to start even when warmed up.
Can a carbureted engine be reliable?

When did Chevy stop making carbureted engines?

The fuel bowl within the carburetor has a float inside; this may also cause flooding if the bowl has a leak or the float is set too high.
Can a fuel injected engine start a carbureted engine?
