Thanks for the tips, I do have a new hook assembly on it's way. The old one is pretty scratched up and worn. I was doing most everything else. I will have to check the feed dogs and foot pressure.The tension disc looked good and smooth. I may have to play with the threading tension on the bobbin as the tension knob for it is frozen. I got a new bobbin case.

I got a good deal on my juki I am a rookie on a machine. It did need a motor, and a good cleaning. I got that and I had a couple good passes on two layers of 5 oz. Leather. Then things went crazy. I'm now having the thread being caught by the bobbin case. I think I got the timing close but after watching Uwe's video(THANKs for doing that) I'll break out some tools and try it again. It is not as easy to see things on my model. One other issue I'm having is the tension seems to not be consistent occasionally it will just lock it up. (I know this could be most of my problem.)

Thanks R8R ill give it a try now at first I couldn’t find the marks I should be good.

Yes it is

Now that I found the marks, I am not clear where the wheel should be in relation to this. I can put the mark there every time with the wheel but that seems like it would not be adjusted. I took the hook assembly off to clean. So I am resetting everything. In the first picture where should the wheel be as far as say the thread take up lever or is there another reference point to for the “bottom of the cycle”

I am struggling with this new iPad to copy and paste the link

It does have the right needle. I did find the reference Mark's while trying to take a picture, let me see if I can get it with that. Thanks for the response.

I have just acquired a juki dcs 246, I got a manual online. The manual says to set the needle height by the mark on the needle shaft. When I do this it is not even close to the hook. Anybody else have a machine like this? Any other reference for setting the hook timing?
