Re: Stalling Problem

When it stalls and won't restart, have you pulled the air cleaner off and seen whether you're squirting gas from the jets as you crank? Can you get a squirt of fuel when you pump the accelerator? It's important to know where the fuel flow is stopping...

How does it perform when it stalls? Is it like someone shut off the ignition suddenly? Or does it run roughly just before it quits?

When you're trying to start it after a stall, does it ever indicate it's close to starting with a few cylinders firing and/or slightly faster cranking? Or does it just crank and crank like it would on a cold day after sitting for two weeks?

The next time it quits and won't restart, try spraying a QUICK shot of starting fluid down the throat of the carb and see if it starts or comes closer to running, if so, you definitely have a lack of fuel issue. If it won't fire at all on starting fluid, it's either ignition or an over-supply of fuel. Check for spark carefully and then re-evaluate. If it's an under-supply of fuel, see if you can get it to start by cranking it and firmly placing your hand over the air horn and choking the thing, it may surprise you and fire up.

One issue we've seen that drove us nuts until we discovered it was similar-- the car would start fine and then a block later would quit and wouldn't restart. It turned out to be a dirty gas tank-- the pickup in the tank would get clogged by a large piece of sediment in the tank and completely cut off flow to the pump and carb. Once it sat for an hour or two, the piece would fall off the tube and you could start and rev the car just fine, but the moment you sloshed gas around by taking a turn or accelerating, boom! The car would die.
