The 912S has a much higher compression than the 914 (and 912). Although
never owned a 912S it was my understanding that the starting issues have
to do with this higher compression, which makes cranking the engine much
harder with much more jolts and kicks.
I guess a larger battery and retarding the ignition during starting
might help a bit.
