You should also have a spring on the trottle linkage that is pushed foward to the ball cup and compressed a little with a collar.

Is everything else as I described?

If so, and your only problem is that the carb won't close...you can loosen the throttle arm on the carb and roll it to the outside of the truck(toward the servo). Shouldn't take much. Also you can unsrcew the ball cup a little...that should push the carb barrel closed alittle.



Where did you get that motor?

I know this is obvious, but sometimes the obvious is overlooked. Have you checked to make sure the idle set screw is adjusted correctly?

Thankx for the pics my truck looks just like that.I wonder if where the brake rod goes on the servo horn if i need to move what hole its in because of the movement on the new carb.I dont know im guessing.

How is your throttle arm positioned? In those pics you can see it's rather close to the engine head, which they really need to be. If you have it say pointing up and down then when it gets towards full travel of the servo the plastic arm on the carb pulls outward rather than sideways to open the carb.

Look at the third pic, that angle is the angle you want to shoot for while it's setting in the idle position. Just loosen the nut up holding the low speed needle assembly, then rotate the arm to that position, and tighten the nut again.

You might even try replacing the spring on the throttle linkage with a piece of fuel tubing for a little more pushing power.

You can't replace the spring on the throttle part of the linkage because you need it to collapse when you hit the brakes. The fuel tubing also won't push the carb arm closed when the servo stops at neutral like a spring will when it's setup properly.
