Features

  • You may be more satisfied with an instrumentThe dial is large enough, the pressure relief valve makes measuring so easy, and the tube with adapters for different connectors is an additional level of comfort. With many accessories for every size you need. The meter is easy to read and holds the pressure until reset with a button.
  • Wide application The kit has different adapters for different hole diameters. The meter is analog with a quick separation that works easily and quickly locks into the tube. Used to find TDC on a #1 cylinder for head sealing work. The kit also contains a spark plug tester. It is a diagnostic tool used to diagnose ignition or engine outboard engine problems, as well as faults in the fuel delivery system. It fits any engine with spark plugs.
  • Perfect replacement Several other accessories are included to work with most thread sizes and there are two quick-insert rubber adapters that keep you in place during the crank of the motor. For inline engines with 4 and 6 cylinders it would be easy to perform a quick test.
  • Great package has a nice rubber case to keep it protected, as it inevitably falls and is shaken. The variety of adapters for the candle hole and which are all equipped with an O ring for good sealing.
  • An indispensable tool this is a must to determine the overall state of the engine and see if there is anything causing problems with the car in progress. If you have low compression, your car does not start properly or does not work properly. Ignition misfires can also cause the engine to become inoperable, in which case you can use a plug engine ignition tester. If a spark is being sent, spark plug ignition tester will mirror the spark and light up, and you can diagnose faults such as dirty spark plugs, poor spark plug connections, damaged cables, defect points, etc.

  • Compression testing
Color: RED
I liked the kit because you can test 2 cycle and 4 cycle engines. It works and is reasonably priced. I’m not a full time mechanic so can’t give a long term review but for occasional use it is worth the money.

  • works good
Color: RED
Excellent for small 2 cycle engines But besure you understand what you need to do to Prep the engine under test. It will help you find leaky Bearing seals, Rings that are not tight against cylinder, or scarred Cylinders (did you look?) Holes in Pistons ect.

Does what i needed it to do. and is pretty accurate. compared it to one a friend has that is much more expensive and got the same pressure readings. so I would say its spot on.

  • Utter crap useless
Color: RED
Do not buy any of these cheaper units, they are sll the same, terrible quality fittings and highly inaccurate gauge, totally a waste if money and returned. Fo you sell a favor, watching some you tube videos before buying a compression tester.
