Classic/Antique Car Repair: 1964 Chevy pickup, chevy pickup, vacuum hose


Question
Hi. I just bought a 1964 Chevy truck. It seemed to run really well when I first
purchased it, but now it seems to be running really roughly (what my Dad
called "missing") and smelling like gas. Also, I'm not sure I'm starting it
correctly--I've never used a manual choke and am flooding it every time I
start it. Could you give me some tips on starting a car with a manual choke,
and tell me what you think is going on with the gas smell and "missing" while
it's running? I'd so appreciate any help you can offer,

Answer
You did not tell me what engine you have, but I will assume some things.

First rule of manual choke, if you don't need it, don't use it.

Second rule: use sparingly. Start the engine turning first, then pull choke for about 1-2 seconds and then push it back in. It should start.

Think of the choke as a primer for a pump. You generally just need to get it started and then it will go on its on.

All a choke does is restrict the fresh air flow to the carb so that more pull is placed on the gas ports. Generally does not take much. Manuals are more effective than automatic chokes.

gas smell/missing: Not knowing what engine you have, I don't know what carb you have. The old one barrels leaked alot and would probably need a rebuild kit.

A bad vacuum hose will cause the same problem.

Let me know if you want more specifics.
