So now I know why the valve clearance had been increased so much - it hadn't! Turns out if you check the clearances on the back of the cam on the exhaust decompressor cam the decompressor is in the right position to hold the valve open a fraction (as it should during starting) - lesson learnt!
After a recheck the shim is too big by 0.08 so I'll sort a new one out tomorrow.
Next step is to have the injector checked for flow rate and new filter fitted.
