I just spent a couple of hours trying to put the rear handle back together on this thing. there is a spring that hooks into a hole on the trigger and also keeps upward pressure on the palm safety. I cannot for the life of me get that thing to stay working. after a few test pulls of the trigger, the palm safety fails to come back up. the thing is a nightmare to line up for assembly also. I have the IPL, but it isn't very helpful.

assembly is not mentioned in either the PM1000 or the P100 service manuals. unfortunately, although I took lots of disassembly photos, I was unable to even see how the spring originally was installed as everything popped apart when I opened it a few weeks ago.

hoping I'm just doing something stupid, and someone can enlighten me. the red arrow in the 3rd pic is where I'm assuming the long leg of the spring hooks in. I'm also assuming the short leg of the spring is what holds the palm safety up.

This may or may not (probably not) help with the saw handle assembly, but on a small McCulloch that I fixed the spring was attached to the same pivot point as the throttle trigger, and then also applied pressure to the throttle safety lever:

Is that a possibility on that PM1000?
