Personally I would do what 124 said re mixture screw.
If you have fast idle which can't be changed by the idle speed screw you MUST have an air leak somewhere.
Whether it is at the boot, mixture screw etc that you will have to determine.
If touching the cable makes it idle up there is not enough slack or it is binding inner to outer. When was the last time the cable was lubed?
Simple faults that can take a while to work out for sure.
Let us know how you all go.
At least the bikes have a choke plate and not a plunger so it should be simpler.
