Throttle springs.
 

Some of you might remember me. I bought a 69 124. I'm trying to get my k301 maintenance all up to date, including new carb,spark plug, coil, point, condenser and etc. I realize how weak my throttle spring is. Where can I buy a brand new one before i steal one off of my air cooled vw. Haha.

Your local Cub Cadet or Kohler dealer can get you what you want. If that is not possible, the sponsors at the top of page will gladly do so.

And sometimes, one just needs to adjust properly, the one they have.
