Thanks. I did not know about this trick. But then Google helped me to look it up, and it did not show up that many places. I found it here by Bernina:

I tried it on some known threads, and I think it will work to discard too small needles. My 207 thread and 140 needle was on the edge. 

But Google directed me to this other similar method as well proposed by Groz-Beckert:

I think this method will accept too small needles.

Google should have sent you right back here for the needle/thread trick.

Hello. I recently purchased a cobra class 18. It sewed for a solid minute until it did not.  The tension is off it seems? I’m using 140 needle with a 207 thread, sewing on 5oz leather. I’ve done more tinkering/diagnosing than actual sewing and feeling a bit down and out at the moment. The needle goes down a few time, then the thread begins to come apart then bunch and breaks. 
What’s happening? Help?

too small a needle.  Go to #160 or #180.
