Does anyone have a suggestion on what to use to keep my carb linkage free?

I have sprayed it with carb cleaner a couple times, but I am getting tired of having to open the hood to get the thing to start.

It happens now just when it is really cold. Like this morning at 7:30 it was about 3 degrees and wouldn't free up when I hit the gas pedal.

Opended up the hood and moved it with my hand and it slowly slipped into high idle and closed up the choke. Started right up after that too.
