Thanks for the input! Wizcrafts, are you saying to change the normal way the spool is inserted into the bobbin? I am a little unclear on that.

Will take pics and post asap. However, it is the top thread tand is pulling up to the leather surface.

I have not been this exact problem discussed. If it has I apologize. I cannot get the upper tension correct on my cb4500. I have made positively sure that it is properly threaded with 207 thread. Proper 23 needle. I test on two pieces 7/8 veg tan. No matter where I set the tension, primary and secondary, the thread does not consistently place the tread into the leather, as designed. A few stitches will be ok and then several at the top of the stitch row. I have checked the entire tension springs and parts. All ok. I have the tension screw adjusted almost off the post and it still is not pulling the thread inside, or below the surface. I know I must be missing something but I don't know what! I am not a newbie. Been sewing many, many years, but not on this type HD machine. Any help will be heartily appreciated! Thanks in advance!

Bladegrinder, I tried your tip on disconnecting the brake and it worked! I adjusted the linkage and it starts slow, runs slow, or I can speed it up. Only downside is making sure to stop stitching you have to push the pedal back to the starting position! There must be also be a way to slow down the startup besides removing the brake! Anyone have any ideas?

Hey, y'all! I don't know how to add photos! DUH! Any guidance appreciated!

Wiz, My machine has the analog servo with a single knob for speed. I have it set on the lowest setting. It has the 3:1 speed reducer. My issue is do I have the pedals and connections set right or is it something else. On start up I have to push on the foot pedal a little too much and then try to slow down to a slow speed. I would like to adjust it where I start slow and it will run slow. I currently don't have it running fast even with the pedal all the way down. BTW, thanks KGG, I think Wiz has nailed what I have.

Hey All, I apologize for not having a profile up, but it doesn't load for some reason. Anyway, I have a new to me CB4500 and I have a problem with the speed, especially starting up. I do not need anything fast, but would like to start slow and keep it slow. However, the foot pedal is something that requires a lot of pressure to start and does not seem to be very sensitive to my foot input. I am doing short length stitching on smallish items, 4" to 8". Is there any way to make the servo start slow and stay slow? I have tried everything I can safely try, but no solution. Advice greatly appreciated.
