[SEL] RE: Update on the Ruston Hornsby - PB 3 - The head is off...

[Paul Pavlinovich]

Good advice Richard - Thanks.

Leaded petrol was available here until the early 90's in some places.

I won't need to wire brush out the lead oxide - it is just falling off - 
I'll pull it out and get rid of it next time I touch the engine.
