When to shut off fuel

I try to shut the valve off after every drive, letting the engine run to the first sign of "fuel-starvation".. the turn the key off. Both spark and idle levers go to a full up position. When I do a start-up I redo the whole procedure.. I guess the routine is a bit much, but so far works for me.!
 
If you don't turn it off, there is the chance that you could fill your garage with all the fuel in your tank due to just a stuck float valve. Turn it off and sleep well.
 
Like Dollar Bill says. I turn valve and let the engine die, then shut key off. No fuel in bowl, no chance of leakage in garage.
 
I turn it off just before pulling into the garage. That way, it quits before filling up the building with exhaust fumes. I used to get confused about what position was open or closed until reading a hint from someone else on the forum. He said; the valve is open when it's like a rocket in a vertical position ready for takeoff.

I just automaticly shut mine off whenever I stop the car and get out.When I was a kid an old woman with an A told me,down and out.If the handle is hanging straight down the fuel is going out.Now I do have a couple of old aftermarket shutoffs,where the lever position is reversed.Parallel to the tank is on,and straight down is off.I don't know where they came from,I got them in buckets of A stuff years ago.I would guess JC Whitney,as the man that had them died long before Ricks came along.
 
The "Instruction Book" makes no mention of the fuel shut off valve. I would think that if it was important to turn it off every time you stopped that it would be mentioned.

Henry moved the valve under the hood in May of 1931. I doubt if the owners opened the hood and shut off the valve every time the car was stopped.

I guess it doesn't hurt to do it...unless it wears the valve out quicker. How often to we check the valve to insure it is actually turning off the fuel?
 
One of my club's car games is to shut off the valve and time how long it takes to have the engine quit running. Amazingly some never stop running... guess they need to rebuild the shut-off as it isn't shutting off!
 
Mine has never leaked, but I don't want to have a bunch of gas on the garage floor some day, so I routinely do shut it off when I park it for any length of time.

There are many things that can be done out of an abundance of caution, and this seems to be one that is regularly practiced. However, I don't know what one gains by shutting it off and running the gas in the carb bowl dry.
 
I always shut it off when it parked in the shop. If I have it out and stop for a few minutes, I leave it open. Last week I forgot to shut it off. When I returned the next morning, the shop smelled of gas fumes. I wiped the bottom of the carb. There was just a small spot on the paper towel. Just as I disconnect the battery after use, it's better to be safe than sorry.
 
What would be the point of running the bowl empty?. To my way of thinking there is no way fuel can leak once the valve is closed and there isn't anything in the bowl that could be negatively affected by fuel sitting in there, even for extended periods so, why run it dry?.

So the wonderful gas we get these days doesn't dry up in the float bowl??
