Stihl 070 fast idle button popped out

[Dustydave]

Hello everyone, new member here.  I have a 070 and just had a strange thing happen. I was milling a red oak log and had the starting throttle lock engaged.  As I neared the end of the log I squeezed the trigger to release the lock and finish the cut.  I didn't see it pop out but realized it after I went to restart it for another cut. I don't know if I found all the parts. I have a black button and s small spring. I haven't had time to even take a look at the saw since it's been raining.  Does anyone have a picture of the assembly?  And part number?  Thanks

Welcome to our forum Dustydave.

Here's a pic of the 090 rear handle assembly.  The spring(3) centers on a pin(2) and the button(4) snaps onto the end of the pin(2).
