750 Huskey - starting and running....but not stopping...

Well, lots of success today. Got the correct belt for the genny and installed that, put in new solenoid and wired that up as well as installing new switch this has 3 posts as compared to 2 post on old switch but with advice from local tractor repair guru got wiring set up so it works. I was careful to ensure that the black wire from the switch came from the post marked M and connected it to the small nut on the throttle plate (which has an insulating washer and is supposed to run to the magneto to shut it off)...well...nut is there but there is no wire from that nut to the magneto....plus, I have been looking everywhere but cannot find where the magneto is located. This is the Briggs and stratton 7 hp engine. Can you advise as to the location of the magneto and what I need to do to get that wire attached to be able to shut down the engine. I can do it by the ground post on the spark plug but really want it to be wired up right so I can stop and start it without raising the hood - particularly in an emergency situation.

Thank you,


Lee

what model briggs? ..if it has points just run a
wire to the switch from the points...may allready
have a small wire ruuning from points out to the
throttle area some motors have a shutoff built in to
the throttle lever... when it grounds out it kills
the ignition.... if it is a newer motor with
electronic ignition look for the same small wire in
throttle area......when it grounds to engine block
it shuts off...

Your mag armature is under the fan shroud. I would think your starting switch should kill the engine when it's turn to the off position so the points are grounded. That's how mine is wired. Hal

The spark plug coil is located under the motor cap next to the flywheel, but on the outside of the flywheel not under it . The magnets on the flywheel run next to the coil and trigger it. I'm not too sure about on a points system as to where the kill wire is located at. It's either on the coil or under the flywheel on the points. I know that on the older systems , especially on 8-12 hp engines, the wire run out from under the cap and hooks up on a bolt on the side of the motor next to the throttle / carb. area and then a wire runs from there to the key switch. The wire is usually black. On newer Briggs engines from about 1990 on up to todays engine the wire runs from under the cap straight up to the key switch , it's usually black too, but there's a plug that is in series ( inline ) with the wire so you can unplug it to change the coil or motor. The coils in that time period from about 1990 - 2009 is now electronic and the kill wire hooks up on a plug under the coil on the coil itself. It's usually black too. They made a few electronic coils for the older points system motors to do away with the points when the electronic coils were invented . So your motor may have come out with a points system and later converted to a electronic system by use of an electronic coil or the little electronic " box " that you could also get to change some of the old points coils over to an electronic coil but without actually replacing the old points coil. You just disconnected the points from the coil and hooked the little " box " up to the old coil and therefore converting it over to electronic.

I alread posted a picture in response to one of your earlier questions. If you don't see any wire near where I put that X, then maybe it's been removed. It attaches to the wire that runs from the armature to the breaker points and . . . looking from the outide, should be coming out from behind the flywheel. If the wire has been removed, you have to pull the flyhwee off to reinstall it, or make a new one.

Thank you, I am thinking the wire has been removed/or broken off? - have to look again tomorrow - your diagram is very useful - I am just not looking in the right place on the engine.
