I can confirm that this works well. I learned it 20 years ago on my first car, a '65 Corvair. It was an 'old lady' car, and this trick is a good first step if you're buying a car that had only been used to go to and from the shops. Because the Corvair was a downdraught carb, I used our old coke bottle with the 'sprinkle' ironing end to drip water so that I didn't get too much in there. My dad's white Corolla was parked next to the exhaust, and was covered in soot! oops.
I've also done a redex decoke on a 2 stroke engine. What that involved was pouring redex into the engine through the spark plug holes. Turning the engine over a few times with the plugs out to coat everything and pump out any excess. let it sit overnight, turn the engine by hand slowly to make sure its not locked, then start up, making sure there is nothing valuable (like one's father's car) next to the exhaust. This is best done at night, when the neighbours can't see the cloud of smoke.
