I put it all back together and started it up, but was getting a bit of white smoke (in hindsight probably nothing out the normal for a cold start). I thought it might be running a bit rich, as a result of accidently turning the bolt/actuator the cam fits on half a turn or so, so decided to try and turn it back half a turn and see what it was like, getting a bit dark so was in a bit of a rush and I have not put it on square and sheered the bolt off and damaged the cam

You can see the sheered bolt/actuator in the middle of the picture and the damaged cam. (I knew I should have had a beer instead tonight)
I am thinking a second hand pump may be in order

Any advice greatly appreciated
