    this is an old pb-650 echo blower. It refuses to start after 1 hour of any rain what so ever. My echo trimmer and edger start fine, they are all mounted on my open trailer. About 1-2 hours after the rain stops the blower will once again start and run. Any idea what is going on?

    sounds like the water is causing something to ground out like the cut-off switch

    Marc may be on to something, Also make sure the plug wire boot is tight on the wire so water can't enter around it.

    All else fails, Keep a box of trash bags in your truck, When it looks like rain tie one over it.

    the plug boot is on but I can see water inside the clear plastic tubing that is arounf the spark plug wire granted there is still a black plastic covering before the raw wire this may be wet.

    by cut off switch you mean the throttle trigger?

    How about water into the carb/fuel line or water soaking the air filter not allowing air in. not sure if these can even happen just by rain alone nor do I know if they would cause a non start issue.

    It could be water on the air filter. I had a Husq. hedge clipper that would not start if the Air filter got wet. Pull the filter out next time it happens to see if it will run without it. If it does then you will know if that is the problem.

    Bingo....that is exactly what happens to our two 650 units they suck rain into the air filter.

    On the pb 650 if you throttle down to nothing I believe the on/off is at the end of the arc. If it is somewhere else I have not found it.

    Will do, that is as soon as I find a replacement boot, the boot rusted off.
