worn piston rings most common problem, but sticking valves, leaking head gaskets can also cause this concern.
sounds like your engine needs a valve job worn piston rings would also cause low compression ,but not cause the backfireing
Maybe a bad valve
Bad are burnt intake or exhaust valve. Pistion rings broken, Burned pistion. Blown head gasket. That is all that would cause no compression are a loss of compression.
The movement of the piston from BDC to TDC.
Defective spark plug, spark plug wire, burnt valve, or blown head gasket. On some vehicles with a coil for each plug, it can be a defective coil. On this particular vehicle, it can only be a spark plug, wire, injector, or low compression in that cylinder.
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
High compression is usually caused by either excessive carbon build up, excessive fuel being injected or oil or coolant getting into the cylinder.
Bad plug? Bad wire? Bad piston or valve (do a compression test)
maybe you need a new head gasket?
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.
If it is causing the cylinder to misfire, yes.
A "Bad cylinder" or "dead cylinder" is a cylinder with Low compression psi. Symptoms: rough running low power can cause high oil consumption
