many thanks. i piut a new o ring on the distributor. the one i got was from a generic o ring assortment box that my local auto part supply shop had behind the counter. despite aligning the key type metal rotor, it was still pretty difficult to pop in - but eventually it made that slight cork popping sound and the body of the dizzy became flush with the block. i understand that the K11 is notorious for leaking there. Happy progress though. Cheers
