I recently purchased a 10 for $50, and it seems to not have any spark. So I tried to clean the points, this did nothing, so I assumed that it was because of the ignition module. My first question is, is there any other options as to why it would have no spark? And if it is the module, do you guys feel it would be worth the price of one to fix the mower.

If it has points there shouldn't be any type of module. It is the SSI (solid state ignition) units that are expensive to fix.

Does yours have an automotive style coil? I am assuming this is the HH100 engine with external points right?

If the unit has points, you are in luck. Generally, points units are much cheaper to fix than the ones with the Solid State.

First thing is to make sure the points are opening and closing properly. Make sure it has continuity when they are closed and are not grounding out when open.

Next, pull the tins and clean the magnets and coil pickups. A light film of rust can develop and kill your spark.
Set the gap between the magnets and the pickup with a couple of business cards. It used to be one thick one, but cards have gotten thinner.

Disconnect the kill wire from the engine ( I think you would have had to move it at least to get the tins off anyways) and turn it over. I check for spark by using a pair of locking pliers or such and locking it on its side to the tin. Just don't get carried away with the pliers.

At this point, you should have spark. If not, we need to delve a little further.

Do you have a manual for that 10. If you don't you can find them in our Manuals section. Take a look at the wiring diagram and make sure you don't have a wiring problem. 50$ is a good price for a 10. They are a nice classic GT.

Well I clearly didn't know what I was talking about when I said points. From what you guys said I can tell that I am working with a solid state ignition I just didn't know what to call it. I think I will look up the wiring diagram like you said, I'm hoping that this isn't a $200 dollar fix

Do these have any effect on the spark? I notice one is shorter than the other.

Those two pins make this a probable expensive fix if it isn't something simple.
Do a search in this forum for Tickle Test and also check out the website http://enginesandmagnets.com/index.html

Overnight solutions has a drop in replacement and there are several other options. First thing first is to disconnect the kill wire fron the CDI and see if you now have spark. If not, that's bad.

There are lots of testing procedures at that website I listed above but the nuts and bolts of it is either build a CDI replacement yourself or buy a replacement system.

Just throwing this out, you may consider a repower with one of the HF/Northern tools engine. May be cheaper than fixing the bad ignition module.

Do you think a Koehler would fit? Like a k301 or one of that style?

Anything that has the crank size to fit the pulley, and that can be placed to where the engine pulley is the same distance from the variable pulley, it will work. The crank center can even be higher or lower, but the distance must be very close so your belts will work proper.

Well I've decided that I'm going to keep the original engine. After reading up on the chrysler control moduel system I think I'm going to attempt it. But I feel that this maybe way over me head when it comes to how to wire up the whole system, more say the trigger and the magnet. I feel that it will be the hardest part to assemble out of the whole system. Does anyone have any tips on how to wire it together, or anything to look for or be aware if? Thanks, Nate
