I have a Toro Powerclear 2-stroke, I do residential driveways and I find that sometimes it won't start again after just using it 3 minutes prior, my house are close by. It starts fine when cold, with the choke & 2 pumps, when hot I usually never have to choke or prime it, but sometimes it just won't start. Recently I have been letting it run for 1 minute after use to cool down and I think it helps, anyone else have this problem? The plug seems fine, fuel filter clean, always fresh gas, proper mix, its only a year or two old. Its an intermittent problem and only happens when hot and then restarted shortly after.
