Yes, if your timing is slow the take-up lever is trying to pull the thread up before it's all the way around the hook & can cause the problem.

The longer throw like your is better,you get more lift on the feet as they walk to clear thicker foam or to climb over a higher seam.

Is the feed dog coming above the needle plate enough?If so you could elongate the slot for the stitch length screw so it goes down alittle more,you also want to check that the feed dog isn't hitting in the front or back of the needle plate.There's an adjustment on the lower feed shaft that sets it.

Even IF it didn't sew it would be worth more than that!

I still have some #2,3,31/2 & 4 needles.alot of people keep the old needle if they break the hook off & reuse it for an awl (with minor sharpening)

I've used a trigger pull guage 1-1.5 Lb pull is all you need on the bobbin & around 5Lb on the top thread.

They are usually adjustable so you can match what ever stitch length your using.

Most of these motors were 220V 3ph,you'll usually have to keep the air cylinder & get an air switch to hook up to the lift cylinder for a foot lift.Some machines that didn't have air lift had a knee bracket on them.

Looks like one thickness of leather try sewing at least 2 or more & see what happens.

Size 69-138 was sewn w/a DIA point 207-346 S-point

@FSForgeThe largest thread I would recommend for this machine is size#138.There is a screw above the screw that holds the needle in that allows you to move the needle clamp left to right,just loosen & adjust as needed.

@falcon45 Size #25 is from US & size#200 is metric so both # are the same size,we do have these in stock.

When the outside foot lifts it will feel like a "bind" due to the foot pressure on the foot,lift the foot & turn the machine & see how it feels.

You can loosen the 2 screws that hold the hook saddle & move it slightly to the right.

Before you do anything take a hacksaw blade & lightly mark @ the bottom of the needle clamp(the part w/2 screws under the faceplate)where the the position is now,then make another mark 7/16" or 11mm lower,this is the difference in length between the two,then you can change it real easy if you want to go back to the shorter needles.

Yes,they discontinued the #202671 yrs ago BUT, I can get one for a Consew that is longer & has the high lift,sell for $20.00 + post.

Yes,you can run it with one needle(sewing with the rightside will work best) for a single stitch BUT you'll still have the wide foot to deal with.We have a customer doing auto upholstery with a 30" single needle 144w & we sold it to them yrs ago & it works great.You just need to adjust the tensions(loosen both the upper & lower) to make it work.

@cynthiab Yes,on the 155 the stitch length eccentric is made that way so it makes a longer stitch & the hand lifter is also taller for the higher foot lift.

@Tastech Great job there!!

You could re-drill the holes & move it down.

Yes,this is a drip pan that catches the oil that drips off of the machine,the hole had a jar to catch the oil,if you put some newspaper or paper towels on the bottom of the it will keep it from running out ntil you find something that will fit on the hole or else plug it. The button on the left is for stitch length,the other one is for the safety clutch. That belt will work but they do stretch after a while & might need to be shortened. The takeup can be brazed & would be alot easier than trying to replace it,a good braze job will hold for years. Here's a manual for it . 211g165 manual.pdf

The hole in the outside is different but it would fit if you wanted to re-drill it.Consew,Juki,Brother & alot of clone machines all use the more common Singer styled feet.Most of the Adlers & Pfaff's have to use the ones made for the brand.

That's correct.

You might want to check the feet again with the feed dog down only this time tilt the machine back in the table,it's possible on this type of machine for the knee lifter to need adjusting,if it's still not going all the way down you'll have to take the end cover off.Take the foot off,loosen the clamp on the pressure foot bar & push the pressure bar down a few mm,re-tighten the clamp screw,put the foot on & check with the paper again.
