Hello Mr Davis, and thanks for your post - it is a fairly old engine! Piston is still a good tight fit, no score marks on the bore - hope I can get it running.

Have just searched the forum for info about Joe Carroll's guide to fitting a breakerless coil to the mower, but couldn't find it, even though other members have made reference to it. Any chance of somebody directing me to the posts - or even giving a quick description of how to do it?

When I had a closer look at the coil, it is very rusted and some of the laminations are seperating.

And ah!! Also sprayed some WD40 into the pull-start clutch - just before I read the post about NOT doing that. So, how do I dismantle the clutch please?

Oh the joys of being impatient and a newbie.....

Thanks again, Jeff49
