troy bilt trimmer

Have a Troy Bilt 4 cycle trimmer. Model TB525CS. Quit running on me today. When I tried to re start it was no compression at all. Is it worth fixing?

    Take off valve cover and check the valves.

    Probably easiest to check and make sure piston is moving first then check the valves. Check travel of valves.

    I'm taking it apart after work. Anything inparticuliar to look for with these valves. If they're bad think I'll get a new trimmer. Cylinder is around $65.00.

    To have no compression, piston not moving or valve not closing. Just make sure starter is engaging flywheel, have seen pawns break off and not engage.
