If the machine was supposed to have an oil pan, I would think you would not be able to successfully use it without one. It would be like trying to drive a car without an oil pan. You could try squirting oil into it every mile, but the machine would eventually quit because it requires a constant source of oil.

Try contacting the manufacturer:

Hook To Needle Timing For Consew 226

Servicing the Timing is NOT a home fix

The new black will go to the old black, the new white will go to the old tan, the green will hook to the frame (case) or a screw there by the area where the new wires go into the case.

You may want to lean the machine back and look very, very close for a very small piece of thread jammed in that race way. Resetting the timing is something you can do but first look for the simple stuff.

Go to www.consew.com and download the parts list for the 224 Consew. It's the same as the 226 for parts. Or, go to www.diamondneedle.com. They have nearly every part you're likely to need. I got bobbin case screws, a hook, some metal reusable bobbins, and some needles, all at very reasonable prices.

I can not get the top thread to pick up the bobbin thread on a machine I have just bought .It was sewing fine and then the bobbin ran out. I have tried every which way but nothing works which way should the bobbin be winding

You may have bent the needle, replace that first.
Have you wound a new bobbin? Sometimes they wind poorly.
Check the hook race for thread "nests". (Bobbin casing)
