Sounds like the valves are not closing properly. Something in the valve train is damaged. Could be a bent or broken valve, broken valve spring, broken or bent rocker arm, bent push rod, etc. Low compression combined with back firing thru intake would indicate a damaged intake valve component and back firing thru the exhaust would indicate a damaged exhaust valve.
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.
It could be a few things. Mostly likely a leaking head gasket, worn out piston, piston rings or cylinder.
To repair a Briggs & Stratton 4.5 hp engine with low compression, first, perform a compression test to confirm the issue. If compression is low, check for potential causes such as worn piston rings, a damaged cylinder, or a blown head gasket. You can remove the cylinder head to inspect these components, replacing any damaged parts. Reassemble the engine, ensuring all gaskets are properly sealed, and retest the compression to verify the repair.

When a Hyundai is losing compression in its engine the car will not run properly. Symptoms of low compression are misfires, stalls, and overheating.
worn or broken compression rings engine needs a rebuild
To detect low compression in an engine, you can perform a compression test using a compression gauge. Remove the spark plugs, insert the gauge into the cylinder, and crank the engine to measure the pressure; low readings indicate potential issues. Additionally, a leak-down test can help identify where compression is lost, whether through valves, piston rings, or gaskets. Observing symptoms like rough idling, poor acceleration, or excessive exhaust smoke may also suggest low compression.
What causes a car to jerk while driving can be based on many factors. A car can sputter due to engine compression issues, bad transmission, engine misfire, bad spark plugs or even low fuel.
It depends on why the compression is low. Assuming you checked compression with a gauge causes could include a stuck valve or valves, blown head gasket, cracked head or bad rings and seals. Repair requirements in order are a valve job, a new head gasket installation, a new or rebuilt head, a new or rebuilt engine.
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.
The repair depends on what is causing the low compression. Low compression can be caused by a blown head gasket, cracked cylinder head, burnt or damaged valves, worn or cracked piston rings, scored block cylinders. It's kind of hard to imagine that an engine would have low compression on all 6 cylinders unless something major is wrong, or the compression gauge is not measuring properly.
