my early non cdi smokes but has good power.I am not sure what the cause is but I have a later cdi motor . Will the head work from it?
Jim

 

Yes they will.

 

I just use my old point setup in the newer cdi head,right?
Jim

 

Correct...

 

It will change but you may run into an issue with the cam length on the CDI cam
I have run into issue when changing to an aftermarket Perf cam
I know the internal part of the cam is direct fit but where the advance mecanism fits
The older points cam is shorter
Not a problem if that is the case use the cam with the points ignition
I hope this makes sense to you
Good luck Ray
