The new one should be here this week. Thanks!

First thank you very much for the replies so far. They have been super helpful. I popped off the lower tensioner and inspected. Everything looked normal so I put it back together and inspected the upper tensioner. There is a small groove as pictured, could that cause issues? I can replace if needed. i also rethreaded as suggested, hoping it did it right. I took pics of everything. I did a test on two layers and the results were very good. You can see the groove in the needle bar guide, new one is in the way.

Just the top most tensioner. I must say it has a lot of tension even when backed out most of the way. I should probably pull the top and bobbin tensioners out to inspect further. I'll do that and report back.

This machine has a lot of run time. I can see the needle bar thread guide is almost worn completely through. I bought a replacement guide, but I’m wondering if any of the other guides or tensioner are prone to wear that could cause this? Or is this simply a setup and tuning issue?

I tried a #18 and 20 with the 69 thread. It still behaves the same. I noticed the thread is not down in the bobbin tensioner, you can see it in the pic I posted above. After fiddling with it I was able to get the thread to slide down into the tensioner. Feeling the top and bottom tension the top is still significantly more tight. I can back it out but it is still uneven. I can’t seem to tighten the bottom any more. here is a few pics of some tests I ran tonight. There are a bunch of runs, note where I’m pointing with the screwdriver.

I'll give it a shot tonight and report back. Thank you!

Hello, First off I should note I am a sewing novice, but did a fair bit of research on my thread tension issue. I recently picked up a Consew 225 for some light leather and vinyl work. So far it's been working well but the thread tension adjustments seem a little off. First I'm sewing with #69 thread, and #16 needle. The upper tension adjustment seems like it's pretty tight, even if I back the adjustment off. The lower tension is much looser, and the adjustment screw is tightened all the way. What I'm finding is that the bobbin thread is laying flat. If I just the top tension it will pull it in a bit but I can still see the top of the thread loop. I'd like to try to even the tensions out, but it seems like the top tension is too much unless it's backed near all the way off. Maybe I'm getting excessive drag on the top tensioner? Any guidance here would be much appreciated. I'm going to upload a few pictures of my setup.

So I just read the manual and attempted the reset procedure again and you were right on the money. The clutch mechanism was in fact disengaged. I had to give the handwheel a bit of a twist to get it to engage again. When I did it last night, I didn't use enough force, I didn't want to damage anything. This time, I heard a click/clunk and then it started working as expected. Wow thanks for posting this video. This is super helpful!

I thought that might be the issue. It appears there is a button to push to reset it. That didn't really do much. But I'll take another glance at the manual as you suggested to make sure I'm doing it right. I'll take some pictures as well.

I'm happy to inspect, but not sure which component is the clutch?

Hello, I am hoping to find someone that can guide me in the right direction on a Consew 225. I just bought it second hand and it appears to have issues with the feed mechanism. This is a non reverse machine. When I rotate the hand wheel in the forward direction the feed dogs walking foot move very little, or not at all. However, if I rotate the machine in reverse, the feed mechanisms work. One thing I notice is that the shaft that controls the feed is only engaged in one direction (reverse). Spin in the correct forward direction, it doesn't really move. I've recorded two videos of the mechanics of the machine, hopefully someone has seen this before and clue me in on what might be wrong. part 1 part 2
