Default Engine trouble with 350 small block crate motor

I am having trouble starting my car. I haven't driven it in a while. When i went to start it, i pumped the accelerator and the car turned over but wouldn't start. The accelerator is working b/c I could smell gas after I tried to start it.

Below I attached a photo. the stainless steel line connected to the filter is full of gas. I don't think it (the clear cylinder) is supposed to be flooded like that. I think this is the problem. I was also told the timing belt could be off. can anyone offer advice on how to realign/replace the timing belt? I never done that before.

Whoa, don't jump to conclusions. Try holding the throttle open as you turn the motor over, it might just be flooded.

Its not April 1 so this must be a real topic.

A small block chevy does not have a timing belt. If it ran well the last time you started it is highly unlikely the timing chain is off. (it is a major effort to install a new timing chain - Google)

The ignition timing might be off, but again highly unlikely if it ran well the last time you ran it.

The glass fuel filter full of fuel is normal. Recommend you have a steel one installed as the glass tends to break allowing gas the spew all over a hot engine compartment.

Sounds like you just flooded it. Try starting with the gas pedal all the way open for 5-10 seconds(the classic method to clear a flood) or a squirt of some starting fluid down the carb. If it does not start with starting fluid then it is likely an ignition issue.

Recommend you take it to someone that knows these older engines as if you listen to the same friend that told you it was a timing belt you will probably end up screwing it up more.

Check for spark as well, might not be getting fire.

A glass filter connected with flexible lines resting up against metal is just asking for the glass to break IMO.

What year is the car? If the electronic tach (74 and newer) doesn't bounce when the engine is cranked, then you have an ignition issue.

Although probably not your problem it looks like it is oriented incorrectly. It says IN on the side leading to the carb.

I have tried holding down the accelerator. Does not work.

I tried holding down the gas pedal all the way down and tried starting it, nothing happens. Like you said i think it may be an ignition problem.

Its a 1974 corvette. The tach needle does bounce when the engine is cranked.

Take the top of the air cleaner off and Make sure you get a squirt of gas down the venturies when you rotate the throttle to wide open.

Pull a spark plug and check for a spark.

How old is the gas??? Old gas that was not treated before storage may not have enough combustibility to start your engine. If the engine starts with starting fluid the the issue is not the ignition. It is a fuel issue. Supply, or the fuel itself.
