    I have since done this to many more of these saws and so far haven’t had any problems with any of them.

    I wish you showed the reassembly. What goes to the engine 1st, the gasket or the metal plate?

    • @wcjcnc

      The gasket goes against the engine. Then the metal plate. Then the muffler.

      The stihl diagram shows the engine then metal plate, gasket, then muffler.

    Since making this video I’ve had several of the saws I’ve done this to come back in for service and other problems and the mufflers on all of them are still mounted solid and haven’t come loose.

    Exhaust issues seem to be a weak point on more than one manufacturer. I was given a Troy_bilt 4 cycle line trimmer. It has an ALUMINUM exhaust baffle. Due to loosening , vibration and heat, the aluminum around one bolt vaporized, leaving a hole around the mounting bolt. The escaping heat then melted part of the plastic guard. Seems some units are made for limited life....lower cost factor leads to early failure. Thanks J K

    Is there a risk of drilling too deep and penetrating the cylinder bore? How deep do you drill to get good thread depth?

    • @wcjcnc

      You only go as deep as the original threads which is plenty deep enough. I’ve had these saws come back for service a year later and the muffler bolts are still tight.

      @@wcjcnc I understand but common taps will not tap the total depth without drilling the hole deeper since the taps are tapered .. I guess they make a bind hole taps

    Should be mounted with a spring and a lip design muffler. Like a dirt bike....

      Robby Clark That would be much better so the vibration wouldn’t break the small screws.
