has anyone experienced this? the decompression stem sheared while the saw was running. i shut it down as soon as i could (2-3 sec) after hearing the unmistakable "choof choof choof". motor stopped w/ a clunk and was locked up til i rotated the flywheel backwards. there is a grove in the stem that 3 ball bearings detent on. snapped at the grove. inside part went into chamber. after removing muffler, sparkplug, and what was left of valve, best i can tell it looks like everything is ok. the seat of the stem has 2 flat spots on the sides maybe .010 deep. i have removed the top of the decomp (everything above the hex shoulder) and tapped the valve guide and screwed a 1/4" screw from the top w/ jb weld to seal off the valve guide and wil install the plug tomorrow. maybe i dodged a bullit.
this is the only saw i have w/ decomp. is this a fluke or is it a common failure?
any comments appreciated 1953greg
