Thank you for your time and expertise. My lack of knowledge caught me out and now you have highlighted I can see the points/condensor on the parts diagram I have downloaded from the B&S website. I am happy to follow your advice re upgrade - presumably I don't need to worry about 'preserving originality' rather like classic cars which also have ignition upgrades so they actually go.
Forgive me, I don't know who I am typing to - do you sell B&S parts and maybe Scott Bonnar parts. I ask because there are a few more bits I need and I have another B&S engine on a slasher wating in the wings - I would prefer to buy from someone on the website.
Presumably I need to get the flywheel off now anyway. You mention tool to remove starter mechanism - is that the splined rod shown in my first picture that the pull cord housing slips over. Is the special tool some kind of universal puller that I could get from Supercheap - if not could you expand on 'tapping it loose'
Oh, by the way the 'stop switch' which should be on the cyl head has been removed and the spark pug connector on the HT lead has a rubber cover on it. All looks good.
Regards
