Thanks julie,
Just trying to sort out some piles of 'left-overs' and accumulated parts in the shed so great to know what they actually are for starters!
The spare engine was really useful for some miscellaneous bits and pieces but had clearly seen a very colourful life before I bought it.
Seller originally said it was a complete engine, running without any rattles ... when I looked at it there was no sump fitted and all the cam chain parts had been removed!
I guess it was quiet but certainly not running.
Hopefully will get some time to sort out what is left and in reasonable condition so maybe someone will have use for some other parts.
Cheers,
Andy
