Even though the photo was taken in portrait, 4chan decided to be gay and fake and post it on it's side.

I've attached another copy, with a clear UP orientation mark. The red arrow points at the tab you probably need to bend down. The white painted area is over the throttle link, which showns in your photo from the other (left) side.

This photo is an extreme close-up from the right side, level with the governor spring.

The throttle link attaches at the greatest movement point - the tip of the arm. The spring attaches in the hole to the left of that, in the other hole.
