Small Engines (Lawn Mowers, etc.): redmax leaf blower, emery cloth, carbeurator

Question
I have a Redmax EB7001 thats almost 4 years old. When I got it used it worked great. Then little by little I had to pull it more and more in order for it to start. Finally one day it just shut off. I took apart the carbeurator and cleaned it out. I noticed after cleaning the carb. that the machine wasn't getting any spark. I checked all the wiring, and still it won't start. Any suggestions...

Answer
yes first thing is take the coil off the motor and clean it with emery cloth and put it back together make sure when you space the coil against the flywheel you use a index card that will give you the perfect gap try that and let me know if that works if not explain what is going on at the time thanks
