Flipping Timmy maintenance

Hi, after a recent possum catch, one of my Flipping Timmys keeps going off on its own shortly after I’ve reset it. The mechanism must be bent. Has anyone experienced this and can suggest a fix? Thanks.

When you set it have you used the plastic slider? I found when I did that it would go off straight away, so better just to slide it out of the way. Hope that makes sense! Is that any help? cheers …

You may know this, but the lure rod is bent/curved forward to increase sensitivity and curved backwards to reduce it. The sensitivity does need to be reset from time-to-time. I try to make the trap as sensitive as possible without having it trigger spontaneously.
