The tune-up kit that I purchased worked great. My leaf blower was running slow. A friend said I may need a tune- up. I went online and purchased one from your website. I watched a video on their website to see where the fuel filter was located. It actually was in the gas tank and not an inline filter. The whole process to replace the sparkplug, air and fuel filter took 10 minutes. The leaf blower is running like new again.
