I will have a look later, Steve.
Judging some of mine, I would say a large hammer and cold chisel was the usual "spanner".

Steve,
That size is 3/4"W or 7/8"BS.

Last time I checked the valve clearence I used a metric spanner (don´t remember exactly think it was around 30 or a 32mm). Please measure the hexagon and you know, what you need!
All my WW and AF spanners won´t fit right!
