Years ago I used  " Plumbers goop" adheseve and clamped the magnet back in where it was ,  Then I drilled and countersunk 8 holes in the flywheel outside circumference that allowed 8/32 countersunk screw heads to push through the holes and pass through to   the tips   ( or sides ) of those curved magnet shoes . then had a very experienced welder , tig the screw ends to the tip of the pole pieces  ( all of then ) Sorry I don't have photo ,   did'nt get hot where the glue was ,so it worked out with out issue ,   I have 57 scooter manual with magnets on alternate position also but all my phelon mags have the magnets symetrical ,   Only two magnets in the right place are needed for spark    the other two augment ( I love that word ,,,, been wanting to use it all week ! ) the lighting output  ,,  I'm sure couterweight is on opposite side .

  Betcha It's an old Zundapp !    metric screw sizes  ( or 26 tpi british standard cycle )  would  tell the country of origin ,   ( certainly servicycle influenced )   Interesting enigma .

 I agree ,  Lots of simplex bicycle hootseewhatsees ,  but this can't be no servicycle part .      Good fodder for guesswork though ,

   Hello and thank you for loading these for our viewing ,    the phelon flywheel there  ,,  kinda looks odd    does it show  4 magnets on one side with a counterweight on the opposite side ?      never saw one like that before ,  looks like an updated way to handle the a.c. electrics , All the best ,,   Larry   

Wife sez that my crankcases smell better than the other stuff I cook ! 

 Hello !   I hope you don't mind me asking ,,   Does the seat spring support you O.K. ?my servicycle spring is way too weak for my skinny butt ( 170  lbs)   keeps hitting the fender if I don't dodge cigarette butts ,   Engine looks frankenstein , but should do alright if it's tight   that early belt setup might drive you nuts at first ( like it did me)  once plumbed up , it does alright ,   Please don't hesitate to ask stuff ,  these engines are very " different"  and have specific idiosynchrocies b( hope I spelled that right )   thank you for the excellent photos and good luck with your project ,    Larry.

Hi there ,,, for what it's worth ,   My old titled 1958 scooter had the early style spring tensioner pully and the early style bolt on smaller diameter rear wheel pulley ,   I remember it also having the 150 cc decal on the headlight shell and the 150 cc cylinder and piston,   ( I remember ordering rings from Hastings corp.  the size was 2 3/16    by 5/64 )    I can"t for the life of me tell you why that stayed in my brain !!  I sold the scooter to a fellow on California named Bill Powell. ( I think maybe 1973 )   Best wishes on your project
