Just ordered my Cowboy 4500. Looking forward to putting it to work.

...

remove that cover there is a screw in there that on mine had started backing loose and thus was causing the stitch length in reverse to be longer then they were in forward and sometimes at odd lengths.

...

Thank you MADMAX22, there is really only one easy to get to bolt under the cover on the back of the machine.

After i tightened it a bit the stitches in back and forward direction became equal in length and the stitch lever became somewhat tighter to operate.

I am attaching a picture of that bolt. Is it the same thing you have done?

Unless you over-oil the stuff at the front of the head where the needle bar is and end up with oil dripping all over your work. Not that I'd know of course... whistle.gif

Amazing how the oil will slide down that bar in no time and three drops turns into a puddle.

Yeah thats the one. My back stitching was fine at first but that bold had loosened a bit and I was having a few issues but once tightened up the lever was tighter and more consistant and the back stitching was pretty much dead on.

Yeah thats the one. ....

I jinxed it... vent back to the machine and the very first back stitch got longer again. I almost ready to blame the machine! :)

I am curious if you were able to correct the problem of uneven back-stitching and if it has been a problem for many others?

I am sorry for the delayed response, my problem was the presser foot tension.

It was too low. Bob actually told me to check the tension but I thought it was OK.

Leather was sliding under the foot. I was using oil tanned leather and it is quite slippery to begin with because of oil.

On top of it the feed dog and the presser foot are very smooth and naturally do not provide a lot of traction.

It is a trade off: you get traction with teeth on the feed dog and the presser foot or you get no "bulldozer" marks on leather.

In the attempt to make less presser foot imprints on my work i decreased the pressure and that created the problem...

It seems to be OK when the tension knob is above the machine head by about an inch.

I do not know about others.

To test your tension please take a test piece and start stitching forward, then while you doing that switch in reverse. Pull the piece slightly towards yourself at all times.

If the tension is too low you will see significant difference in stitch length forward vs. reverse.

I believe you should be able to switch in reverse at any time of stitching cycle.

Thank you so much. That really clarified what was happening and how to check for the correct tension.
