How can I get these nuts off of the throttle so I can slide in the kickdown linkage

It looks like the op haden't seen the double nut thing before and when it wouldn't come loose the question came out. Now, on the flip side, us crusty old guys that have been wrenching on stuff for a half century can't believe someone couldn't get those 2 nuts loose. For whatever reason. No disrespect. We just forgot how much we didn't know when we started. Even the most knowledgeable here learn new things often.
