Basically I have a weber 40 and at a certain throttle position (not RPM) it makes a high pitched constant squeak, annoyingly this happens to be at the position that I cruise in at 30mph anyone any ideas what it could be? Thanks

The only time I have come across this is on a DCOE where on a light throttle where there is high manifold vacuum, and the noise was air leaking in past the carb to manifold sealing rings (misab Plates), and this was a high pitched squeel. Have you replaced/checked yours are not perrished or incorrectly setup on the mounting washers.
