    Last year it was (little wonder 8hp push blower, snapper 17 hp wb, year before shindawia back pack, today shindaiwa blue backpack blower). I work alone so it was not the mix/gas. Can you really over work these things? Heard the rings popping around today then crap!!! What am i doing wrong?

    I've never had one fail...any brand. You must be doing something wrong.

    I know, have a lawnboy that says 32:1 been running strong for years (10+). Anyone heard of a cool down period between uses ,my equipment can run for 6+hours a day nonstop. (small motors, backpack.etc.)

    Well if you're putting mix/gas in a motor, yeah, I can kind of see why it would fail,
    that stuff has got to be rough on the commutator, not to mention the brushes.

    Now then, for your sanity I'll go ahead and assume you're speaking of engines...
    The mix is 50:1, correct?

    How are you making sure that this mix is, indeed, 50:1?
    Also what kind of oil are you running in the Wb, synthetic?

    Perhaps cheap gas, too.

    If you were to get a thermal overload from shutting them off too early it usually manifests it's self in the form of bad coils. It's not a bad idea to let them idle for a minute or two before you shut an engine off. It even advises to do so in every Stihl manual I have.

    Specifically, what fuel and oil are you using? What is the mix ratio in ounces and gallons?
