- Glazed or Splintered Cylinder Walls.
- Weakened Timing Belt or Cracked Chain.
- Worn Piston Rings.
- Damaged Valve Springs, Seats and Retainers.

Why is there no compression in my engine?
When you get to the point of checking the compression levels, you find that there is no loss of pressure on any of the cylinders. This can leave you scratching your head. Before you grab your tools and start tearing into the engine, take a moment, and look at the spark plugs.
What causes a loss of compression on a spark plug?
Even a hairline and almost microscopic crack in the ceramic part of a sparkplug can be enough to cause a loss of compression and a noticeable loss of performance. If your compression gauge confirms that you have good compression in all the cylinders, the first suspect should be the spark plugs.
Why does my saw have spark, gas, and compression?
I have spark, and after repeated cranking the plug is moist with fuel, so I think I have spark, fuel, and compression, but it won’t even sputter, nothing at all. I thought about pulling the carb and doing a rebuild, since that’s fairly easy to do but I’m at a loss as to why this saw ran fine one day, then two weeks later wouldn’t even sputter.
What causes low compression in an ATV and how to fix it?
If your compression gauge confirms that you have good compression in all the cylinders, the first suspect should be the spark plugs. The easiest fix is to replace all the spark plugs on your ATV engine and see if it fixes your problem. Spark Plugs for your ATV are cheap so this can be a good place to try and get lucky.

Can you have compression, spark, fuel, and air but not go?
You can have good compression, ignition, and fuel and still not get a 2 cycle to pop off and run. If you have a major air leak into the crankcase, you will never get it to start and may never even get it to pop. Make sure there are no air leaks around anything that attaches to the crankcase and that the top and bottom seal are in place.
