Briggs & Stratton ignition question

My point exactly. That's average. It does depend on which model coil you have but most do run around $40. The cheapest is about $35.

Wayne have you got any experience with the performer series of onan engines?

I have a severe no fuel problem in the carburetor, I guess I will have to rebuild it .

If the flywheel key is sheared... you will *still* have spark, but it will not be occuring at the correct time to fire the engine. As long as the magnets are passing the coil face, a spark will be generated, the key is for proper timing. Ken.

grey matter" this time. You are indeed correct. Two part statement.... Points and then "no points" . :-) I do agree with you about the points type ignition being easy to "tune up" for easy starts.... I've never been a fan of the electronic world, and now with all the computers they're installing in lawn tractors, etc., it's a losing battle.... . BTW, Briggs' new self starter, where it winds up a spring on shut-down so the spring starts the engine the next times it's used, and then re-winds the spring on shut down again for the next time (forget what they call it)... have you done any work on them? What do you think of the concept? Just asking.... Ken.

Nope. The position of the flywheel will be out of phase with the points which are actuated by the cam on the crank. When the coil passes the magnet no spark will be produced unless the points open and close at the correct time. The electronic version simply senses the reversal of polarity in the coil and fires the plug - regardless of the position of the flywheel. Ken (the other one :).

I may have missed this piece of advice: The problem could be that the shorting wire is grounded someplace along the line. This is an additional wire connected to the points that goes somewhere- maybe to the carb, maybe to a start-stop switch. If it's shorted to ground or if the switch it is hooked to has failed, then the points will be grounded and you get no spark.

I'll need to wash my mouth out after this, as I have to admit to owning an Ozzie mower, namely a Victa GTS (guaranteed to start). It came standard with a module. When I mean gentle, I mean Little Ole Lady capable. I've never seen a Briggs that could come close to easy first try starting as the Victa.

Yes it's what's on my welder unfortunately.

It's not that hard. I don't go to the trouble of removing the carb on engines like this (it's usually a lot of trouble to do). Instead I just remove the 4 screws which hold the carb together and rebuild it in place.

What exactly is your problem?

I can't say that I've even heard of it. I am out in the boonies in many ways. Few folks around here who could afford something like that and if they could then they've got enough lawn to need a rider.

That doesn't surprise me but I must admit that they've improved over the years. One example has to be primer bulbs. They are one of the few true improvements that's ever came up in the last few years. Most of the engines are getting worse IMHO.

Sometimes the spark plug wire deteriorates, especially corrosion at the crimped on fitting attachment. Try removing that piece, cleaning the wire core, and re-attaching the crimped on connector.

Coils almost never fail, easy enough to find a scrap engine and switch coils. Make sure the kill wire is not accidently grounded.

Points need to be completely clean. Condensers occaisionally fail. Make sure all connections are not corroded.

The add-on unit I installed on my old tiller engine(which I no longer own) would spark reliably enough to start on the second pull virtually every time, and it did not take any more of a pull than the original point ignition. The only thing that would make it easier to start would be battery ignition. It started at least as easily as the mower with factory "magnetronic" ignition.

And if the timing is not correct, the points open when there is no coil exitation, and you get no spark. That simple. And pretty fussy in my experience.

This is the concept of the "abrisz" point. For an excellent discussion, see:

For points mags to work, the variation in magnetic flux has to coincide with the operation of the points.

You probably didn't notice it. It's not that much a concern for anybody with any kind of strength at all. But the fact remains that it takes more rpms for that type to spark than the other style ignitions. The difference isn't enough to notice unless you're trying to fix a mower for a little old lady who can barely pull it.

so I notice if an engine is hard starting - for a week or two after as well.
