Hey thanks for my warm welcome Jack, a cooler one would nice though,

Sorry for slow reply!

The rails aren't cracked as yet, cotter pin was tight as!

Would you recommend plating up the under side of rails now or wait till they crack? Keeping the cotter pin tight!

As I said this was my fathers machine bought in the early seventies, used for probably 14 years before moving to a new house with unsuitable lawn. All original and almost complete, missing the plate on the handlebar frown
The engine is a Kirby HK30 h4-5a, does anyone know the difference between this model and the h4-4a as I haven't seen too much of other 5a's

Cheers Grame
