At least one, could be many more depending on size of engine.
Blow by. Compression is passing the rings.

50 Cent wears two rings in his "Right There" video, one on each hand.
without knowing the exact details of your loss of compression I can offer this : if the engine was flooded the excess fuel will wash the rings of oil and you will have no ring seal. to check this , remove the spark plugs and squirt about a spoon full of oil into the cylinder. let it sit a couple minutes now recheck your compression. if you have some now, reinstall the spark plus and try starting the engine. It could be a blown head gasket!

compression rings on pistons are worn out or broken
You will have an improvement in engine performance and an increase in compression unless the compression rings on the pistons need replacement .
smalltime here, generally your compression rings on your pistons are shot ormabey worse case senerio cracked block! hope this helps. smalltime.

Changing the pistons will NOT fix an oil problem UNLESS you have a hole in the piston, which would cause many more problems as well. Placing new rings on the pistons, along with honing the cylinder walls (which is necessary if you are replacing rings) WILL allow the cylinder to seal better, improving compression and stopping oil slipping past the oil ring. It would be wise to check valve guides and seals as well if you decide to change the rings.
Poor compression rings on the pistons will allow gasoline to seep into the oil sump.
Compression rings are made of cast iron.
I am not a professional mechanic but i think that you might have blown rings on the pistons that have oil on the spark plugs. what is probably happening is the rings are bad so, you are not getting good if any compression in the cylinders and the oil on the plugs is probably from a bad oil control ring also on the pistons and the oil is getting past the pistons onto the plugs.
1) If there is no battery power to turn the engine and make a spark and pump fuel. 2) If there is no fuel supply. 3) If there is no spark when the engine turns. 4) If the spark is mistimed compared with the compression phase of the pistons. 5) If there is low or no compression because of burned valves, broken rings, or holed pistons.
Yes. Boring the cylinders means that you have made the hole bigger. Although it's only a few thousandths of an inch difference, that is quite a lot when the piston is traveling through there HOPEFULLY for a long time. If you bore the cylinder without putting in the appropriate sized pistons & rings you will have NO compression and the engine won't run, and even if it did, it would wear out VERY quickly. So, YES, you do need to put in new pistons and rings when you bore the cylinders. And while you're at it, if you live in a high altitude (4,000 ft elevation or above) you can usually select pistons that will raise your compression by 1 point without causing trouble for the computer.
2 compression rings and one oil control ( helps scrap excess oil off cylinder walls)
The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.
