Points upgrade?

Recommended Posts

biggin

Has anyone changed from points to the electronic ignition on their single cylinder kohler? ypunuzud.jpg

I went to my local dealer to get some "tune up" supplies and he said that they haven't sold too many point sets lately and guys are upgrading to the ignition module instead, not having to clean and adjust points isn't a big deal but upgrading to this doesn't sound too bad.

Sounds interesting, waiting on comments.

I think you will find they will only replace the points in a magneto ignition. And then they only work if there is one magnet in the flywheel. Two magnets and they won't work.

I went this way when I rebuilt my K-301 6 years ago-never looked back!-Timing staying the same -good performance-Al

I have one on a k91 powering a RJ. Right from installing it the difference was obvious. Engine stars much quicker usually on first pull if there is gas in bowl. Timing is also automatically set and stays that way. Nothing to wear.

OVA 2, Mega-Fire and OEM Kohler Electronic Transistorized Solid State Ignition Modules [Return to a previous section]

  • nova.gifmegafire.gif2575710s.jpgThere is absolutely no difference how these modules work. They all work the same. Kind of like the difference between the Chevy, Dodge and Ford vehicles. These are universal and high-performance. They improve engine performance by stabilizing the spark, much like crank trigger ignition does. The NOVA 2 and Mega-Fire modules have a durable die-cast aluminum housing. They all produce a hot spark even at cranking speeds, allows the coil to produce 100% voltage. Weather-proof and very reliable. Ignition timing is automatically set. No kick-back and no timing adjustment required. Works excellent with virtually any magneto ignition coil!
  • Suitable for use with most 2 leg or 3 leg magneto coils and with a flywheel having one or two magnets mounted internally or externally, and with coil mounted underneath or outside of flywheel. Works great regardless of the polarity of the magnets, too. Works on most lawn mowers, chain saws, trimmers, garden tillers, snow throwers, brush cutters, one or two cylinder outboard boat motors, etc., with points and condenser ignition. But will not work with most Stihl trimmers and chain saws. Usually, the coil don't need replacing when substituting the points and condenser with one of these solid state modules. If the engine ran, then the coil is obviously good.
  • Works only with magneto type ignition coils originally connected to contact points and a condenser. They will not work with solid state ignition (CDI) coils, battery ignition coils or with flywheels having a ring of magnets mounted internally to which the ignition coil (mounted underneath flywheel also) operates off of, such as the bigger aluminum block Tecumseh engines (8hp and up). (With the module, as each magnet passes the coil, it'll produce a spark. And if the spark don't occur at the precise time with the piston at a certain position in the cylinder, the engine will either "kick back" or will not run.) If the magnets for the charging system won't interfere with the magneto coil(s), then these modules should work well. But if the magneto coil(s) operate off the same magnets for the charging system, then neither module won't work. The modules senses when the magnet passes the coil and that's when it makes the spark. If a bunch of magnets continually pass the coil, then the coil will produce an array of sparks.
  • How the timing is automatically set and how it works: First of all, with points, the point gap determines where the ignition timing is set (on systems with a fixed or non-adjustable ignition coil). Therefore, the spark occurs when the magnet in the flywheel passes the coil laminations the moment the points open. But with no points, the magnet still passes the coil laminations at the same moment, which sends an electrical current through a transistor and circuitry within the NOVA 2 module. This current is sent in the form of a signal to the module; within, a transistor opens the primary circuit in the coil and the spark occurs. All this happens at the speed of electricity. The conventional points and condenser ignition system is less responsive.
  • Each module has two wire connections. One wire connects to the ignition coil and the other wire connects to the ground of the engine with use of a supplied mounting screw. Comes with detailed instructions. Click here for installation instructions.

Thanks for the info, I've got a 73' 16hp Kohler, so it should work for me I hope, several years before they went to cdi

If I read the above info correctly, it only works on magneto type, not battery ignition.

Correct, it does not work with battery ignition.

 

Should have mentioned on last post, this information is from Brian Miller's site. Greatest source of information anywhere for Kohler engines.

Thanks guys, I was led to believe by the salesman that it worked on all points and breaker motors, good to know it only works for magneto engines.

I went with this also on my K-301 several years ago. The point saver works great and David Kirk is a great guy to deal with.

Tried it on my pull start HH60...could never get it to work :confusion-scratchheadblue: .....

I put David Kirk's point saver on my C100 and noticed a positive difference - quicker starting, smoother running.

Look at the situation from the perspective of the sensor. Its logic is simple. When I see a magnet, I fire the coil.

 

If your HH60 or K series has several magnets on the flywheel, the module is always firing the coil. In the case of the K series tri pole magnets, that would be 18 times in one revolution of the flywheel, 72 times within the 4 cycle sequence of the K engine.

 

Single magnet flywheels, no problem.

Even dual magnet flywheels that may fire the coil during the beginning of the intake cycle, no real issue. But 72 times during 4 cycle operation - nope.

Hummmmm, I might check into this for a 1100 Clinton. The spark is very weak and intermitent

I kinda get the whole to many magnets thing, but who can tell me which my engine has? Do I need points saver or electronic ignition?

Model # K241AS. Spec # 46766d

Do you have a 1977 B-100 8-speed model 71-10K801? The spec number posted for this model is a bit different - K241S-46756D

 

 

The spec number is what really identifies the engine.

So if you go to an Automotive type charging system and remove all but one magnet, will it work with electric ignition?

Hi Gary

You have battery ignition. The battery powers the ignition coil which should be mounted on the flywheel cover next to the carburetor. The points are under a small tin cover on the front right side of the engine near the bottom so the point saver will work for you.

The location of the magnet for electronic ignition determines the ignition timing. Good luck trying to figure that out.

Garry you're a gent, thank you. Just a pity as the that point saver costs more than the electronic ingnition.

Horse46, did the Point Saver work for your K241 C101 ???   I have one I'm working on and thought if it works, I may try it and not have to fuss with points.  Thanks.

This post is five years old. you may be better off sending a PM.

Yes quite an old post, I had to re read it to see what it was about! No i didn't go down this route and TBH I have never had to re adjust the points either. It always starts and run fine as long as the battery is charged.
