I have an old rotor tiller with a 5 hp briggs on it. I'm not sure of the year, its at least as old as the 1970's. The problem is, it has no spark. I took the engine cover off to check the coil for bad connections but nothing seems to be out of the ordinary. I noticed some wires that go under the fly wheel and from some of the other posts i've read on here, there's a points ignition under there. How the heck do you get the fly wheel off?? That may not even be the problem but i'd still like to know how. Is there a way to test the coil? Any thoughts?? Thanks.

Go to your local Briggs dealer and tell them you want a trigger coil kit to take the place of your points & condenser they will know what you want. This comes with instructions on how to mount it to your same coil,No need to pull the flywheel just snip the wires as close to the flywheel as possible and go tilling.
This kit is only a couple dollars more than points & cond. and less hassle !

About how much is that kit?? U still use the same coil with with this kit?? Any way to know if the coil is bad?? This thing has absolutely no spark but i did get a little jolt one time when i touched the wire when looking for spark. Not a big jolt but enough to be noticable. Thanks for the help!

I believe its in the 12.00 to 14.00 range,And you use the same coil,Its not likely the coil if you got a little jolt,There is a coil tester that plugs in the wall that I use,Just ask your dealer if he has a way to test it for you.

There isn't any kind of generator under the fly-wheel where the points are that can go bad???

NO,There is only a set of points and Condenser under the flywheel inside a small type box with a little tin cover over them to keep dirt out.

When you remove the coil to install this kit make sure you reinstall it facing the same way you took it out,And adjust the coil air gap with any business card.

My dealer web has been acting up but I finally got on,The Briggs part number is 394970 I don't know if you can get it on line or not,I know Briggs only sells to dealers on line.

This is a long URL but that is how it come out it is over 100 characters long so it may not copy right. Briggs now does sell parts online though Briggs Power Shop site.

I don't mean to sound doubting but how did you know what part number to tell me?? I didn't give you the part number for my engine. Or is that a part thats used on all kinds of briggs from that era?? I just don't want to order the wrong part.. Thanks!

The model # is 130902
Type is# 0152-01
Code # 76100600 which means its a 1976 i presume??

I've Been in the business for 14yrs now and I pretty much know my model numbers by H.P.,And this part fits many many engines of this era.I have installed many of these kits on 3 hp to 12 hp engines,If you question the part number have the dealer look it up ! Yes Its a 76 engine

Good luck

Back then, a lot the same parts would work on most of the similar type engines...

i would junk the thing and get new engine just for the simple reason that it is just a matter of time before that old antique starts to cost real money.

but that is just one mans opinion.

Well this is my opinion; A tiller doesn't see the use a mower does every week or so therefor a tiller has a longer life span,I would spend the 14.00 or so and run it till it blows then worry about a new engine or tiller.
And this man may not have your kind of money either.

Thanks guys, i shall go to a dealer and try to aquire this part. If they act like they don't know what i'm talking about(either because they'd rather that i buy a new machine from them or they actually don't know), then i'll just order it online. If this doesn't fix it, i don't see what else could be causing it. Not much to these things. Thanks!!!

Well, i got the new part , put it in and it gave me a nice fat blue spark. Tried starting it and it fired up on the 3rd pull. Runs alot smoother than it used to. Thanks for the help!
