yes i did used to have an engine on mbe as said above but mine was running 967 and i am afraid i dont have any diagrams for the 956
www.sbdev.co.uk are the ppl to speak to on this one there very helpfull and i am sure they will be able to send something over if you could e-mail me the diagrams you have i can have a look throu them if you would like
only time i ever had a problem with mine not starting was what the coilpack was duff other than that nothing
