Hi Simon,

You mention the centre bolt, Do you mean the bolt in the centre of the magneto sprocket? If so, the bolt should pull the sprocket off the taper on the magneto shaft, if it is an auto advance/retard unit. If it is a manual advance then use a puller to remove the sprocket and the mag can then be withdrawn from the engine,

Regards, Rob.

Hi Simon,

I hope that you have only made the threat without carrying it out as the crankcase is the only part which will suffer, I recall that the problem of stcking auto advance units was covered here a few months ago so maybe a search of the theads will give you some ideas to free it,

Good luck, Rob.
