Many thanks.
The aim was just a quick clean up rather than a complete rebuild. If I stop now I can always go back a do a proper rebuild later when I have a bit more money to spend. Re-seating the valves, freeing the governor flap and replacing the plug will probably give me another years smokey service without doing any permanent damage to the unit.
Mean while I'll pick up the parts over the coming months so I can hide them in the monthly outgoings.
