I had my RedMax strapped to my back and my Husqvarna strapped to my chest today as I cruised around town pushing 20 mph on my bicycle. I was having a blast and met up with two other LCO's that I saw along the road who were a bit curious and wanted to test it out. Anyway, as I got back to the house, neither blower would kill so I had to pull the spark plugs. I tried it again a few hours later and still, nothing. I don't know what the problem is.
