Richard Farrant gave me some info which I tried but still no response from the air/fuel mix screw, basically nothing changes when the screw is turned either way?

I have some info on the carby , I will have a look and see what I can find out. Is the screw you are adjusting for the idle mixture only ? Or does the screw affect the fuel ratio over the whole RPM range ?

These carbies were a special design for the military , the manual refers to them as "dustproof". Maybe your fuel pump pressure is too high - have you checked it ? The pump pressure is critical. The CS8 uses a Autovac petrol sucking vacuum can on the dash, its a gravity flow down to the carby . If the fuel pressure on the needle seat is too high ( too much pump pressure in your case ) you will experience problems.
