I am installing a new set of stators, points and condenser in my 74 atc70. The fly wheel keeps rubbing on something and I can't figure out what. I first had the stators reversed from the attached pic. this way it rubs less but still rubbing somewhere. I'm stumped. Help:wondering

Are you torquing down the rotor nut before you test for the rubbing?

Take a black magic marker or sharpie and "paint" the inside of the rotor and the edge that goes against the engine. install the rotor and torque it to spec then pull the motor over a few times, see if you can hear it rubbing, pull the rotor and look for wear marks in the marker/sharpie that you painted on the rotor. If you can hear it rubbing, you should see marks in the ink which will give you an idea of where it's rubbing. If you don't hear it rubbing and there are no marks in the ink you should be good to go. Clean off the ink with carb cleaner or something similar, put it together and off you go.

I'd check a few things.
Make sure this new setup works on the early 70's. The early and late 70s have a different width stator and flywheel.
Make sure the clip that holds down the wiring is nice and flat. These will rub on the flywheel inner edge.
Check the inside of the flywheel for rub marks. It's easier to see.
Make sure the inside of the flywheel is spotless with nothing stuck to the magnets (fillings and such)
Make sure the flywheel starter cage bolts are not too long. Someone may have put in a bodgy one back in the day

Thanks for the feedback. I have attached a pic of the flywheel and you can see scraping. I'm wondering if your idea that the stators may be for the later year 70.

The stators are rubbing,,,,I believe you can adjust the stators a little , each stator has 2 phillip screws holding them to the plate. Simply loosen the screws and push the stator as far as it can go to the center and tighten so it doesn't rub against the flywheel.

Good idea.
Even enlarge the holes slightly for more adjustment.

Also check that points bolt holding on the lead. You may have to turned it over so the nut points down.

good ideas. Is there any harm if I grind off some of metal part that sticks up on the end of the stators?

Ok, Here's the deal.
Greenhuman - I took your advise and drilled larger holes in the individual stator coils.
It still rubbed.
Discovered it was rubbing on the metal clip that holds the wires in place where they head up out of the case. I needed to cut off the top section of the clip, then file it down real good and tap it in tight with large screw driver and hammer. No more rubbing:D
I think it was a combination of the metal clip and the stators rubbing. It was a matter of fixing one then fixing the next.
Thanks for your ideas and feedback.:idea:

All good

Oh, it's flat now. It was confusing. I think your idea of drilling larger holes so I could push the stator coils closer toward the middle did help. I would fix one rub and then realize there was more than one. The rubbing is all gone now. Just not getting any spark....................mymint87

Now it's time to adjust your points... use the lightbulb method described in the service manual. You'll be able to get the timing perfect that way.

Thanks for the feedback. The spark problem was there with the cdi set up and now with this set up. Flying W is helping me sort it out.
