    More than likely the nozzles are worn. Drop your needles .5 to start

    Most of them have the mid range burble, drop your needles a hair

    Is this the reed notch/spacer burbling you are referring too?

    It didn't burble today, it was between -13f and -15f.

    That tells me it needs to be leaned out a tad. Just like Max and Shaggy mentioned. You yourself just confirmed it though. I'd probably start by dropping the needles a 1/2 spot. Adjust(or not) washer position after you check things out from that run.
