PaulI do work on both possibility first with the Evinrude 50HP and the
   second with the CB400 Honda and the Honda look much more easy to fit
   with Tracy damper with little machining it fit perfectly ove the
   spline hub and clear the 20 rivet heads with the flywheel back radius
   the flywheel can be assembly with 6 bolts or 6 rivets.The flywheel
   does not need to be balanced but the Evinrude one it will needed.I do
   have a problem and i am wondering if the RX_7 flywheel fit on the RX_8
   i dont know if someone have a loose flywheel so he can loan me and i
   will pay the freight or take dimension of the big hole and the 6 bolts
   circle and hole size,i look to me it can fit but i want to be sure
   unless i have to built a special damper to fit the RX_8 one.Paul on
   the photo you send me it does not have the big spacer between the
   flywheel and the crankshaft but it have one on the RX_8 ,i wont
   install it .

    Jean,   It looks a very elegant way to have a solid state ignition
 system and alternator fitted, but if you remove the spacer under the
 flywheel will it not move the flywheel away from the starter (unless you
 can also move the starter)?

 Michael Hart sent the dimensions on Tracy's adapter plate.

 "These are the measurements that you requested:
 A=1.85"
 B=1.16"
 C=6.2"
   D I was not sure if you want center of rivet to the opposite center of rivet
 which is 5-56" or the diameter of the ridge inside the rivets which is 4.91"
 E=2.87"
 G=.386"
 F=4.45"

         John Burey,

As per Paul recent photo showing the flywheel and engine space it shown without this spacer and as per the dimension he supply i came up to his dimension without the spacer,i look on the RX-7 aircraft engine conversion they dont use this spacer may be someone can answer to this. Thank's for the dimensions but i need the RX-7 flywheel center hole ans surrounding attached bolts holes to compare with the RX-8 so i can switch to the RX-7 flywheel and still use the Tracy damper plate because the rubber bushing holes on flywheel are more far apart and to close of the starter gear

Junk yard engines are cheap Jean. You need to get one.
