BR800 throttle setting lever

[B737capt]

I have a fairly new BR800 and this is my 3rd one. What I'm having a problem with is when I use the throttle setting lever as they call it in the owners manual, to wide open, moving the tube left and right blowing leaves pulls on the cable and pulls the motor rpm down. There isn't enough friction to hold the throttle wide open. I took the handle a part but didn't see anything to increase the friction. I haven't had this before on previous units. Anyone else have this issue and found a fix?

Sounds like the throttle cable jacket is not properly locked into the handle retainers.

I'll double-check that, but I didn't see anything out of place when I split the handle. With my finger firm on the trigger, holding it wide open, I can feel tension trying to reduce the rpm through the trigger when waving the tube back and forth. I even slid the handle back on the tube to give it more slack, but it doesn't help.
