Remove the top cover on the saw to expose the spark plug.2. Place the sparkplug wire onto the sparkplug but do not install the spark plug into the cylinder, leave it dangling loose. The spark plug should remain in the spark plug boot.5. If your ignition works you should see blue sparks where the plug is being grounded on a metal surface. Attach one end of alligator clip wire to the spark plug boot, make sure the clip contacts the metal conducting surface inside the boot.4. Hold the metal threaded part of the spark plug in one hand and pull the saw over with the other. Sometimes I use this method in high light situations when I can’t see the spark directly.

How does a chainsaw magneto work?
The magneto creates the electrical charge needed to fire the spark plug, and the spark plug creates the spark inside the combustion chamber to ignite the gasoline (see How Two-stroke Engines Work for details).
Can timing cause no spark?
No, if your engine has a bad timing belt, or timing belt slips, you could still have sparks. Timing refers to the sequence of which events are happening in an engine combustion cycle. Having bad timing can cause problems like poor engine running.

Where is the ignition module located?
The ignition module may be located inside the distributor, on the distributor housing, or mounted to the side of the engine compartment. When a module goes bad, it normally fails totally and the engine won’t run at all. Checking your ignition module is an easy task that requires only the simplest of tools.
Can ECM cause no spark?
It is extremely rare for a no spark condition to be the result of a faulty coil or ECM. Users get fixated on these items and jump to the conclusion they must be responsible for their problem because these items are easy to see and replace.

How do you clean the carburetor on a chainsaw?
Let the chainsaw run at low RPMs/idle for a while. This is to let the cleaner run through the carburetor, the fuel lines, and the idle engine. The cleaner will wipe remove the gummy residue blocking the components to create a clean passageway for the air and fuel. As the RPMs begin to increase, turn down the idle knob.
