“Bubbles” from sewing machine needle

[Cdmel93]

Hi there, I have the green Sailrite leather Machine Can anyone help on why my sewing machine may be doing this? If the leather is dampened or completely dry i get these “bubbles” or “blow outs” I’m using V92 thread and a size 20 needle. It does this regardless if I use one or two layers of 2-3oz leather or 4-6oz leather.

Bubbles?  It would really help if you posted a photo or video of what's happening.  You're using a 135x16 needle, right?

Going out on a limb but are you using leather point needles (LR)? Textile needles blow out bubbles on the underside, whereas leatherpoint ones cut diagonal slots.
