I've just purchased the Cowboy 6900, (4800?) the first electric machine ive ever used. Been quite the learning curve! Mainly teaching my left foot...  Had an Outlaw for several years but found its limits with bag making and thinner leathers. I have made 3 or 4 bags quite successfully and am loving it so far. So much easier and more accurate with 2 hands holding the work

Problem is I had a jam that tripped the clutch. Mistake learned! Reset it but now the stitch length is way too short for the dial numbers and it's not walking the material thru properly. Looks like the dog is sitting too high and maybe not timed right, seems to grab the material and pull it back to the front. It stitches okay so hook timing is good, but a 6 on the dial is only about 2 or 3mm on the leather now.

Something has shifted.

Watched and read everything I can, but not sure what, where and how to adjust to make it right. Help please?

@Trucker, moved this to leather sewing machines. Help Wanted is basically if you're looking to hire someone and requires moderator approval.

Here's an engineers manual on the theCB341 that should work on this model too.

Thanks for that!

That's the detail I need to understand the mechanics and settings of how these things work.

One thing to check before you do any timing,turn the stitch length to "0" & make sure the feed dog in centered in the slot.

So, I've cleaned and oiled the shuttle, measured hook timing, needle height and feed dog height, etc, all to specs. Everything is wicking oil (a little too much down the needle) and it's still well greased.

It sews just fine. Except....

Presser foot won't lift till it's set at about 3 or so, needs to be at about 6 to actually lift enough to move the leather. And stitch length needs to be above 3 or so to even separate the holes. Set on 8 makes a 4.5mm length. Was almost exact to the setting till the clutch tripped. So something has moved. No evidence of teeth broken and no metal bits floating around, and everything is  tight.

Been studying all the linkages and movements, and the books and diagrams, but still not confident enough to start loosening screws until I know exactly what moved? And why?

So can anyone help? Maybe a photo pointing out what to adjust?
