I have a 2001 Yard Machine with a 17.5 hp Briggs on it. Model number is 313707, type 0162-E1. Does anyone have a carburetor linkage diagram? Something is not hooked up right and I can't figure it out. The engine starts right up but it does not want to idle. If you give it gas it will rev up but then it will not want to return to idle. You can move the throttle to fast or slow and it will keep on idling fast. However when you first start it up it seems to idle pretty good. You can manually move the governor at this lower idle and it will rev right up until you remove your finger. I tried using the idle adjust screw and it would make it idle faster. When I back it off instead of the idle dropping it stayed the same. I must have one of the springs installed wrong. Thanks
