Most of the times when you have low compression on one cylinder it's an indication that the head gasket is blown. If more than one cylinder has low compression and is hard to start the you most deffinatly have a blown head gasket
sounds like your engine needs a valve job worn piston rings would also cause low compression ,but not cause the backfireing
A "Bad cylinder" or "dead cylinder" is a cylinder with Low compression psi. Symptoms: rough running low power can cause high oil consumption
Low compression in one cylinder can mean several things. The valves or piston rings may need to be replaced. There may be a crack on the engine, or the head gasket may have blown. The engine should be diagnosed properly to see what exactly is the cause of the low compression.
If it is causing the cylinder to misfire, yes.

You have to take out the cylinder, how low is it, what is the difference
Yes, a malfunctioning Automatic Compression Release (ACR) could potentially cause a Tecumseh OHV17 engine to have low or no cylinder compression. The ACR is designed to relieve compression during starting to make it easier to crank the engine, but if it fails to close properly, it can prevent the necessary compression from building up in the cylinder. Additionally, other factors such as worn piston rings, a blown head gasket, or a damaged valve could also contribute to low compression.
When a jet ski has low compression in one cylinder, first, perform a compression test to confirm the issue. If low compression is verified, inspect for potential causes such as worn piston rings, damaged cylinder walls, or a blown head gasket. It may be necessary to disassemble the engine for further diagnosis and repairs. Addressing the root cause will help restore proper engine function and performance.
Loss of Power
The lack of compression in one cylinder of a Chevy 355 engine could be caused by a number of issues such as a leaking valve, a blown head gasket, a cracked piston, or improper sealing of the piston rings. It is recommended to perform a compression test and further diagnostic tests to identify the exact cause of the low compression in that cylinder.
A bad lifter, worn piston rings/cylinder walls, carbon build up, bent push rod, and a worn cam lobe. A burned valve can also cause low compression.
