Well that was a little easier said than done. As I had issues with the right one not popping up , I looked and one of the small screws holding the face on had come loose. To get at this I had to remove the full coil and then release the troll Mech from that shaft and take completely out
Got the screw back in and tightened both to keep the face back on. Checked the switch and it looked pretty close already.
Reassembled the right one and then adjusted the switch on the left side just by raising the troll up.
The right was was still not activating - Turns out that switch had bent closed - so it sensed this and never popped up. Adjusted it slightly open as the left one is now - and back in action.
Popping up as it’s supposed to and registering hits as it did before. Not too light of a hit but strong enough to make a troll growl !
All is well in the kingdom once again. Play on!
