Pull the starter rope; if you see a bright blue spark jump across the tester window, the spark plug is defective and must be replaced. If there is still no spark, either the coil itself has burned out, or the plug lead is defective.
If you have a tool powered by a gas engine, it has a spark plug. This small but essential part serves to ignite (spark) the engine. It should be checked before you use it in the fall as part of a regular maintenance schedule.
Your spark plug is what ignites the air/fuel mixture. It`s what creates the explosion which makes your engine produce power, so if this isn`t functioning properly for you, then this is the guide for you.
If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
The main purpose of a spark arrestor screen is to prevent ignited gases from leaving the engine. In really dry periods of summer and fall, these heated gases, if they escaped, could start a fire, which, in many areas, can have disastrous, even fatal consequences for the local population.
The parts of a 2-stroke petrol engine work this way, and the parts of a 2-stroke diesel engine work similarly except it has a fuel injector instead of a spark plug.
External rotor motors — also called cup motors — are brushless dc motors that differ from traditional motor designs employing permanent magnets. They excel in driving an array of blower and fan applications.
If there isn`t any spark visible when kicking the engine over, follow these steps: (1) Check the metal cap on top of the spark plug and make sure it is tight. Give it a gentle twist with a pair of pliers if it isn`t. (2) Make sure that the spark plug lead wire is solidly connected to the spark plug cap.

ANSWER : Sounds like your flooding the engine; I did the same thing. Wait a while to let the gas drain back to the tank. Use your primer bulb once and your choke for only ONE pull; then shut off the choke. Pull start without the choke 2-3 times and it should start.

It will not start and has no spark. I pulled the plug and let it hang and had no spark. I did the same thing with a spark plug and still no change. Can anyone help me
ANSWER : First of all- your methods of testing spark are … unsatisfactory.
You need a spark tester and a good unit ground to determine the condition of the module.
For preliminary tests the spark plug needs to be grounded. Insert the plug into the spark plug boot and make sure there is a good connection and make sure the plug is grounded by touching the threaded part of the spark plug to a solid engine component. Usually the cooling fins of the cylinder or head. Once the plug is grounded proplerly then pull the rope and check for fire.
Once you are satisfied that there is no spark then unplug the ground wire from the module and check for spark again. If you have spark then its a switch or bad wire problem. If still no spark then replace the module.
