Hi All
I've boiled the big bits in a 40 gallon barrel full of caustic soda, pressure washed it off and started cleaning it all up.....
First question, I have read that the 8/1 has an aluminium piston with 4 rings, the 6/1 an iron one with 5. I have an iron one with 4 plain rings., it fits well, the top 3 rings 'gapped' at around 20 thou'', the bottom was well worn and 'gapped' at around 90 thou''
Any ideas?
Also at the top of the crankcase is stamped J 84, would this have been a 'witness' from the original builder?
As it's a 'bitza' (1934 ish hopper cooled crank case, Lord know what on top!) what spec. should I rebuild to?, I'd like a 6/1 driving a 4 kva ish alternator............
Cheers Stef
