Timer doesn't always send a signal?

[Y2KNW]

I'm playing the TechNodeFirmaCraft pack, and while I know it's a rather memory intensive pack, I've found that the Timer doesn't always send a signal. The little torch lights, the sound goes off, but no redstone signal is sent.

I'm getting a bit more luck sending the signal by putting a repeater after the timer, but it's still kinda touch and go.
