Well my saw won't stop

Hi folks, yes it's true, been running a 346 in the woods for a couple of years and recently been having real trouble getting it to stop when hot. Just splutters along for a while until it eventually conks out, but can take minutes. Changed the spark plug but doesn't help. But it does seem to stop fine if it's a cold and damp day. Any ideas, should I be cleaning out the cylinder? Been running on Aspen.

The saw shouldn't stop by itself - it should sit idling happily. Turning the switch to the 'stop' position should kill the spark so it stops immediately.

 

If it isn't stopping on the switch, this indicates that the wire is disconnected, either at the switch end or the other end, or has broken somewhere along its length. The fact that it stops when damp but not when hot suggests a poor connection rather than a total break - the water is bridging it.

Thanks, switch end of the connection looks fine, where's the other end? The stop switch works fine just after cold start. Also the idle changes to something more spluttery when hot stopping, it just doesn't cut out.

It could also be the actual contact that has a bit of sawdust wedged inside it, preventing it from short-circuiting the ignition (which is how the stop switch works on all saws).

 

In the meantime, you can stop the saw at any time by putting on the choke.

ITs normally 1 wire which goes from the coil (under the starter cover) to the kill switch.

The kill switch will either be earthed to the body of the saw or via another wire to a grounding point.

 

The wires can chaff and rub over time. Likewise the switch which on huskies normally pop out. Give it all a good clean. Inspect the wires and clean up the switch and contacts between the switch and saw body.

Thanks for the tips, the spade connector on the coil end (blue wire) had some play so cleaned and tightened this. Not got enough wood at home to test properly, but idled for a while and it stopped fine, so hopefully problem solved. Have been using the choke to stop, is this bad for the saw at all?

 

Sympathy to those with starting problems!
