Hi. I just bought a 2002 Scotts 42 inch mower, 17.5 Kohler engine. It won't idle down. I start it and runs full speed . Where would I start looking? Thank you

there's a few things to check. One is that there is actually a throttle plate in the carburetor.. sometimes they can come loose and lodge or pass through the engine, also make sure the linkage is not binding and moves freely.
if that checks out, i would perform a static governor adjustment.
If you can find the model tag on the engine that would be a great help to us so we can give you engine specific information.
