Under the valve cover was the telltale blue color of Abarth valve springs, and an extensively modified rocker assembly running on needle bearings. The before picture:
...and the rocker shaft after cleaning & inspection. As far as I know the stock 695 used a fairly standard Fiat 500 rocker assembly, so this must be a later addition.
Cylinder head was disassembled and thoroughly inspected, and required only minimal work to be put back in good order. No, the valves couldn't be any larger.
The proper Abarth 206 camshaft (tipo 206 was the designation for 695 series engines).
More to come.
