Well success! Did as directed Grumpy, and after finding a spark, did the next step and it started after about 4 pulls. I stopped it after about 20 secs. I then tried to restart it (no choke) but no luck.
I then repeated the step of adding fuel straight into the cylinder, started it up (about 5 pulls) and just let it run, which it was quite happy to do.
The clutch does not seem to disengage the cutting reel to well though. At low speeds it sometimes stops spinning, but at higher revs it engages the reel regardless of the clutch position.
I didn't give it a full work out, but the roller clutch does work, a bit faster than I would care to mow at though. Anyway, I think from here I'll start to pull it down, sandblast and paint the frame, replace what needs replacing, and have the reel sharpened etc.
Ill post updates as things progress.
