I have just scored a A10 crankcase (ZA10 129**) and shaft that had been sitting in a shed for many years, on pulling it apart the conrons where for a A7 (6in BC) the shaft is A10 (84mm stroke)
Has any one come across this before?
I didn't get the barrel or pistons with it so am at a bit of a loss as to what is going on?
It was pretty obvious that it had been working like this, the shaft is in good condition the conrods where a bit of a problem, the PO that did them up had used lock-tight and when I tried to undo them the bolt turned in the conrod and stuffed it.
