I posted to uk.rec.gardening but not had any replies

I have just been given a Suffolk 75G14 petrol lawn mower that has sat in a
dry garage for about 11 years without any use at all.

I have not done anything with it yet apart from pull the starter cord a
couple of times to see if there is any compression. There is, but I realise
that's no indication it will work.

Could someone please let me know what the spark plug gap should be and also
the points gap.

Any other help that you could offer would be gratefully appreciated.
