How are you adjust them?  Should be two screws to work, plus the box slide from side to side.  Things do like to loosen up and slip out of time.  You may have to remove and clean them.

Had same problem after installing new points. New plunger assemblies are no longer available. I scanned eBay for months to locate NOS plunger. Reassembled with new part had same issue. Ugh!!  Finally used small round file on point bracket screw hole. Problem solved! 

Good Luck

Convert your CCKB ignition to electronic ignition from an Onan Performer and never look back. Ditch the points box and block it off. The Performer ignition uses a crank sensor and never needs to be adjusted.

Here is a link on how to do it.

Hey John, I have tried to read that posting several times but it won't let me as I am not a member of Michaels.  I've even tried to become a member JUST to read that posting but for some reason, I can't join.  Is there any way possible you can copy & paste it here or email it to me?  I have your rotary valve PS write up saved as a PDF on my computer.  I'd do the same with this.

I filled out the membership for Michael's about a year ago and never heard back on my confirmation perhaps if a member there could print that page off as a pdf file then convert to a png image file to post for us here on simple tractors.

If your not able to convert a pdf file into an image file just email me the pdf file then I'll do the conversion for you.

As I would also like to change my older Onan from points to electronic ignition.

I agree with John, I've converted multiple motors over to the electronic ignition, worth every penny. I'll take one of my onans with this set up over my vanguard repower any day. The Honda repower on the other hand is a different story. The hondas awesome, my only complaint is the motor doesn't fit the best, the one valve cover rubs on the hood but other then that I love it

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
