I just replaced the distrib on one of these. The rotor came loose and jammed and actually broke the internal distr.shaft! Anyway, there is a thread already on here about timing this motor from about 2-3 months ago. We just set the distrib so that the flat part in the back was parallel to the firewall and it ran great.(Lucky?) (This was after finding TDC of course) Anyway search here a bit and it is explained how to do it right.
