I have a 68 ss12, had the same tech motor # issue also,, I think I did run the model # on the Sears web site, of coarse the motor is no longer available, then I think I went to Parts Tree from there .

Found a round tuit . Hooked a battery up gave it a spin . Starter/Gen works good , but no spark . There is a wire that comes out from behind flywheel that is mounted to air shroud , then another one from mount to nowhere . Does the nowhere wire go to the switch ? In the wire diagram shows a fuse? or something on this run back to the switch . Does it need to be hooked up for spark ? I blew out the shroud , but maybe something ( spider web or mice ) is blocking trigger .

You probably have an early CDI/SSI module system on that one. They are usually a grounded system when you turn switch off. I would pull shroud and take a pic for us. Do not connect any of those wire to 12V+, you will burn up the ignition which is expensive.
go to this website,
down left side click on "sears tractor" then go to next drop down box and scroll down to the 68 SS12 "parts list" manual. Once it loads, you can down load and save to your computer, the 69 manual doesn't have a wiring diagram, should be similar to the 68 though.

I just went through the same problem. The phantom wire goes back to the ign switch. When you turn the ign switch off, it grounds that wire. So just the opposite. Try disconnecting the phantom wire and see if you have spark. If not, try this site, it has good info on trouble shooting your iggy. http://home.earthlin...oller/id11.html

Hi was just wondering would a HH180 fit ? Or does it need mod's
Posted June 10, 2013 - 02:45 PM
Doe It's a OH 180 , its on a Dayton Gen. Free needs carb. the bolt that holds the bowl falls out . Maybe parts for the HH 12 , or fix and sell ?

I think the hood needs raised a scosh and the wiring would need some attention.

The HH120 is a flathead, the OH180 is overhead valve, not going to be a whole lot that will interchange.
The 18 will fit, but will be tight, the front grill may need spaced up and the support bar that goes across top will need to be bent or removed as it will sit right across the rocker box.
Make sure you check the 18 crank, many of the generators used tapered shafts/pulleys, the 12's will not just slide on.

Made it back ,but have been working on a Gibson SD , & a early Economy ( tiller steer ) 23 fb motor . Got some time today to work on the SS12 . Pulled the flywheel (13021 ) well someone has been in here before no key , the wire to the coil was pulled apart . There is still a pcs of wire on the coil side . I am going to add to it and check it out or is there a way to check the coil ? Also need to know size of key don't want to buy a hand full . Coil # 7190 , 8 ,6 hard to tell last # .
Yes I know pic's working on it
