Thanks. Really helpful Andrew

OK. Thanks. The base of the brass one in the new Carrbridge is square so I can get a spanner on it.

Thanks Mech Can I check with you. Do I need to remove the brass port and replace it with the part I photographed? Andrew

I'm fitting a new carb on my King Quad LTF300. From China. Only one I could find in UK. I think it should have 2 vacuum ports. The vacuum port for the petcock is silver coloured. I can feel the pulsing vacuum. Putting the tube to the petcock there operates the petcock100% perfectly. I can't identify the vacuum port for the fuel pump. The new carb is identical to the old EXCEPT that in what I think is the 2nd old fuel vacuum position is a brass upright port with a very small hole. When running, there is no vacuum I can feel and putting the fuel pump vacuum line there does not give a decent fuel flow - only a small trickle. Is this the fuel pump vacuum port - see photo? The carb came with a silver coloured screw-ended 1.5 inch long loose port in the box. See photo. Is it intended that you unscrew the brass port somehow and put in the silver one? I'd really appreciate your help At the moment I can only do 10mph in a stuttering fashion on the level! Andrew Devon UK and put in the silver one?
