Stitching and timing a Consew 226

[vega]

I have a Consew 226R machine. My problem is my bobbin thread gets caught up when I place the needle down to turn a corner or slow around a curve in my leather. I changed the original timing belt awhile ago and recently tried to time the hook and needle, by following a YouTube video. No Luck!! Now the machine isn't picking up the bobbin thread at all! I'm just getting stitch holes from my needle. Can someone tell me how many rotations the bobbin case makes for a stitch? I am grateful for any help I can get.

Have you investigated the old Singer 111 and 211 manuals for insight in timing your Consew.  They certainly share some parts I noticed while looking a stuff for my 211G166.
