Been fiddling and the fuel pump decided not to work, as I removed the fuel bowl from it, a nasty smell of stale petrol appeared . After investigation, the pump was gunked up with a fine brown gunk. Modern petrol is the culprit here , it leaves a brown film on fuel components , it can block jets and cause trouble in petrol tanks .

re: the valve guides , American auto parts in Ballarat have the generic early chevy guides, over 3" long , for $5 each. I will machine them to length .

I also got a aluminium timing gear to fit , I've seen the old fibre gears strip teeth too often .
