What size needle are you using? Also, run the top thread straight through the thread guide on the top of the machine, like in the first picture. My sewing machine mechanic told me to do that with larger thread, but my Consew 226 with a size 22 needle sews fine with 138 with the thread run through the top guide like in the second picture.
If you want to sew with size 270, you need a machine with a larger bobbin, or you'll be changing bobbins every two minutes.
No one lives forever, the trick is creating something that will.
