The worst trouble Ive had was with my 138 white thread. It almost gritty feeling when unwinding from the base, and on all my cones, regardless of thread type, it is much harder to pull thread when its at the bottom of the cone.

A couple of things:

i) Bad spool of thread -- Replace

ii) Poor quality thread -- Replace and buy brand name thread. To add to Wiz's recommendations consider A&E thread. I use this thread in the 16 oz spool size and have never had a problem.

iii) Mounting arrangement of the spool of thread --- If possible could you post a photo of how you have your spool of the thread mounted. The distance from the top of the spool of thread too the thread stand guide hole should be at least 2 times the height of spool of thread.

iv) Dark thread is usually stiffer. Bonded nylon is stiffer then bonded polyester

v) Size of spool of thread can also effect how the thread reacts as it comes off the spool.

vi) Larger spools have less problems with spring memory then smaller spools. More problems with 4oz then with 8 oz which has more problems then 16 oz.

I just want to say that there's a bunch of good information in this topic.

Thank you all for your very astute suggestions... From needle selection to tension suggestions, all are very valid and I looked into all of them. However, last night I removed the cover plate to watch the bobbin threads in action. What I saw was the thread was getting hung up on the little tab on the bobbin case that goes under the feedog plate. Which got me to thinking about this ole machine.  When I bought this machine a few years ago I was told it was a 115.... I'm pretty sure is not. I'm not 100 percent sure what machine this is. The stitch length selector starts at 5 . So, maybe it is a 153 or 154?

So do I have no business trying to run a T208 through this machine?

This leads me to my next question for you wonderful people is... How do I find out what machine I have? The serial numbers have been removed.

I have heard that you can tell by the height of the foot lift. But, if I'm measuring foot lift... Is that measuring done when the presser foot is lifted to move the fabric (lower lift position) or when it is at the high lift position (to disengage the tension disk)? Or is it the height the walking foot lifts while working?

LAST question, I promise. I use 16oz and  8oz  size cones of 92 and 138 thread and I have noticed that the thread spools out with VERY uneven tension from my cones. I have a net on the cones and when the thread is coming from the bottom of the cone it is VERY hard to pull off. I have experimented with sliding the net all the way down until there is only 1/2 inch of net just at the very bottom. That didn't help.  Ive tried to raise or lower my cones to see if that would help, nope. So is there some magical position I should have my cones set at to get a smoother and even pull off? Or are there special cone nets that are better than others?

Singer 111W155   Max. thread to use on machine is #138.  You will have problems w trying to run #207.

Thank you I'm seeing that it is the case
