Have this G62 that ran great for a while but has got to the point where it just will not idle down lower than 1800 to 1900 rpms..now I know that is not to bad an idle but the throttle plate is completely closed and it should not be running at all. I'm sure it has a vacuum leak but where..I have replaced all the gasket and overhauled the carburetor. I started with the needles both at 2 turns out and in or out doesn't seem to solve the problem. I considered the throttle shaft might leak air by but it is not to loose..

any thought out there...
