The gaps at the ignition pick ups may also affect timing. I once checked 
them on a 912 and found them wildly out of spec. possibly they got 
disturbed during engine installation, (there was no cover on the early 
912s) After resetting the engine ran better but the rpm gauge was wildly 
over reading.
