416 w/ 16hp Onan Won't Stay Wide Open???

So when you throttle up to full the throttle just creeps back down.  Am I missing a part or what needs to be done here to keep the throttle where I set it?   Thanks

It's an issue of wear on the throttle lever itself. Sometimes you can squeeze the rivet (*with a pair of vise grips or similar) on the throttle lever to give it a bit more tension, but most people drill out the rivet and replace it with either a 10-32 screw and nut or a 1/4-20 bolt and nut.

Most excellent advise.  Thank you.

Such an easy fox yet I couldn't think of it.  All I could think of was I was missing a spring or how I could rig up another spring to hold it open.

On all my tractors except my GT1642 I have drilled out the rivet and replaced it with a 1/4 - 20 bolt and nylock nut.  Throttle tension is adjustable that way.  Bill.
