I recently aquired a 68s 2.0ltr engine - typ 901/02 serial 4080xx
It's one of the early '68 MY engines with the alu case.
We started to strip it down for a re-build yesterday.
Generally all seems good condition..
some of the cylinders have black deposits / markings on the inner bore..
Can anyone help with what might be the cause of this ?
Any remedies so I can rebuild with confidence.
I'd like to re-use the barrells if at all possible.
The rebuild plans are stock/stock.
Many thanks for opinions
