When starting from cold, try cranking the engine over without the choke out
until the green light goes out, then pull the choke out to fire, this should
stop the knocking as the oil is pumped round the bearings before it fires.
The oil light in my MkIV Spitfire actually comes on for a second or two after
it has fired but there is NO rattle!!! Strange eh!! any ideas?
