Chainsaw Repair

  Good Morning all,

  Loose, missing, cylinder screws are not at all uncommon.  Usually starts with right front.  Have seen this many times.

  Sometimes the threads are destroyed, sometimes not.  The PTO rear and flywheel front screws may be broken or damaged.   Check the crankcase screws also.

  Had a "Red Eye" come to me, "worn out, no impulse."  Two screws missing on PTO side, right front cylinder mount broken off, flywheel side screws backed part way out.  No impulse because cylinder was flopping around on crankcase.

  Not a bad idea to check these screws when doing maintenance.

  Take care, Larry.  HOS.
