I'm not getting any spark on my g-26,is there a way i can check to see if its the ignition coil,source coil,or the spark plug??Thalnks for any help,everything else is complete.I always end up having something go wrong!

Check out the Gas engine forum, you might find some help over there. Also don't forget to check your on/off switch, they too can fail. One more thing, Make sure the red wires going from the mag to coil are firmly connected behind the engine. They tend to be a bit short on length, and it's easy for them to get pulled apart.
