Beyond checking compression, carburetion and ignition, Brad says the single most important test to run on a 2-stroke is a leak-down test. A 2-stroke engine requires a properly sealed block to run right because it uses the crankcase vacuum created from the rising piston to pull the incoming charge into the crankcase; the downward stroke of the piston .

A compression test is simple to learn and only requires a few basic tools. From a mechanical perspective, you will need to know how to properly remove the spark plugs on the vehicle or equipment you are testing and properly disable the ignition system and fuel system, the latter if the vehicle is fuel injected. For carbureted engines, you can choose to disable the fuel supply .

Four-stroke engines can produce much higher compression; check the readings we got for our subject engine, a 2006 Suzuki DF115. Again, the readings should be within 10 PSI of each other.
on two stroke a compression test is quick easy and painless. on a 4 stroke it is a teat on a boar hog. I cannot tell you how many 4 strokes have passed a compression test with leaking heads,leaking valves and stuck rings due to carbon. yet the compression was good and the leakage rate above 70%.Leaf blowers use 2 stroke engines ranging between 30 to 50 cc. While the minimum compression a 2 stroke engine needs to complete the combustion process is 90 psi, you cannot expect a leaf blower with such a low compression reading to produce much power. . Ensure that you have a compression tester that is specifically designed for testing .INNOVA 3612 Compression Tester .
