idle

Newbie here, I put a new carb on Husq YTA 24V48. Throttle linkage seems to be fine, and pulling it back to low does slow it a bit, but not nearly as low as it should be. Is this some kind of governor adjustment, or what??

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
