Thanks Robert - for some reason, even though your post preceded mine, I have only just seen it. As a result I have double checked the starter dogs on the 2 engines I have. They are both parallel. I had assumed taper as that is what I had been led to believe. Interestingly, the spare engine has a dog that will permit a 1/4" drill bit to pass with ease, whereas the engine in the car will allow a 7/32" to pass through it but not a 15/64th" A 1/4" stands no chance.
From what you are saying, it seems that the Roll pin is the better option, though I may need to clear the starter dog with an appropriate reamer (awkward with it being in the car). Having just measured the Roll pin I have been given (by a trusted source) it measures 0.2585" so would seem to be correct for the application.
