Two posts in one day..

Well, I tried getting the engine going - spinning it over with an electric drill gave me a shock from ht lead but nothing through the plug. Cleaned points and got weak spark from plug but no pops or bangs so have decided it's going to be rebuilt

I've taken the barrel off and as you can see, there's quite a carbon build-up

So I'm going to treat it to new piston and barrel and gaskets etc and decode the crankcase.
