Engine shut off switch broken, Craftsman chipper 247.795860

I just got a used 8 HP Craftsman chipper shredder, model 247.795860, Briggs & Stratton engine 190412-6143-01. The engine shut off switch is broken on it, you can just lift it off the body. The switch is not connected to the wire underneath and I can't see how it should be attached. Can someone show me a schematic, tell me how to repair it, or give a part number (it's not shown in the manual)?

Thank you for your help.

The wire that hooks to the switch is a single wire from the Armature-Magneto. I believe it has a spade connector on the end. The switch grounds out the Armature-Magneto, stopping operation. Try a local Briggs & Stratton dealer for a new part.

Here is a link to the engine parts list:

Airman, thanks for the link...it's very detailed and helpful. I've ordered the stop switch.

In the meantime I have taken apart the carburetor and found about a tablespoon of disintegrated aluminum dust and pieces inside...it's fallen apart, holes in the wall, etc., shot, not rebuildable.

This (I hope) is the major problem. Could you give me a rough idea what the cost should be on one of these, and if I have this problem, do you think there will be related problems in the engine (in other words, is it worth it to buy a new carb (rebuilt?) or not)? Also, what would have caused this?

Thank you for your help.

Part number 390323 carburetor retails for $160.00 ouch! Search for “390323 carburetor” and you will find some cheaper online. Look for used locally.

If the engine has been sitting for a long time it may have further problems. Inspect fuel tank for corrosion. Perform evaluation of cylinder/valves, e.g. compression or leak down test. If all of this checks out you will need to weigh cost of repair versus replacement.

Corrosion of carburetor was probably result of water.

202432-0036 or 205332-0536 are replacements for 190412-6143. Look online for best price.


Good luck
