Briggs 4hp Tiller Motor

Hello, as I was tearing down the engine to do a complete rebuild, my coil wire that connects to the coil busted off right at the coil, is there a easy way to fix this? Thanks!!

Post the engine model, type and code, stamped in the metal engine shroud just above the spark plug and someone will have an answer. Have a good one. Geo

Well it is a 4hp Briggs, it is a older engine but has the same principal as newer ones. The wire came off the coil that goes into the points, just wanting to know if I can reconnect it to the coil do I need new, but yeah, thanks. The numbers are 100292 0154-02 73020207. Those are the only numbers I see.

So you have two wires, one to the points and one to the kill? If you just have one wire, it's just a kill wire and the coil is a module = no points.

No, just 1 wire. The kill is a little switch u use to ground out the spark plug. The wire that broke off was the one coming out of the little cover from the points to the coil, broke off right by the coil. I have seen the points, I'm confused cause I have never been good at points anyway.

If you don't want to be dependent of the points, this would be the perfect time to just replace the coil. You can buy a new coil that only has the kill wire and does not need the points. Just clip the points wire off at the cover and forget 'em. If not, you may be able to carve a little of the plastic off around the broken wire just to expose enough to solder the wire back on to it. I've done that on some of the expensive electronic boxes like boat motor CDIs and similar devices with success.

397358 is the part number. Make sure you buy an up to date one with electronic ignition instead of an old stock one made for points. I suggest an original briggs coil. Aftermarket ones rarely last very long in my experience.

Thanks again. So when I get this I just clip the wire coming out from where the points are and that is it? I need no more wires correct? Again thanks, and sorry I'm not up to date on these things.

The only wire you'll need other than the plug wire is the kill wire.

On the kill wire, what does it hook to? I have the metal piece that grounds the plug to kill it, so is that wire needed? Also, I'm looking for rings, and the head and crank gasket, would you happen to know the part numbers on those? Thanks again!! Danny Petersen Sr

On the kill it depends how nice you want to make it. All you have to do is ground the kill wire to kill the engine. You can put a toggle switch on it somewhere. Run the kill in one side of the toggle and the other side of the toggle to ground. Then mark the flip side as off or on. Or you can just buy one of toggles already marked. Dozen difference ways to do it.

If you have the metal flip down piece, then you don't even have to have a kill wire.

For the parts you need, google your model number and you can pull up a parts diagram with numbers for all of your parts from several online parts retailers.

I was afraid of that, they said the rings are unavailable for that model, I even called one place there looking into it and will get back to me. I will wait and see. Thanks for the help, appreciate all of it!

Determine the bore size and ring width and then compare with other sets of rings. If you can find oversize rings, don't rule them out. If they are .010" oversize, you can prepare the bore, and grind the ends of the rings until you obtain the proper end gap when you square the rings in the bore of the engine.
