@AlZilla I tried this already, no lateral movement... @friquant yes, I used a brand new 230 needle as recommanded in engineer's manual and then my usual 160 to check every modification Thank you both of you for your kind words and help through this journey 😅 it helps ! I feel less alone 😆

Yes, it is still all the way to the right, as it was in the begining. I messed up eveything trying to do what @Constabulary was suggesting. It's been the hard way to learn that these screws/settings will only allow me to move feed dog original position from : - Up or down - Back and forth The procedure I should now try is the one suggested by @friquant and it should allow me to move the needle bar block in order to center the needle. This is why I am reluctant. It's clearly the feed dog which should be moved but there is no way to do that. My last option is now to move the whole needle bar block

Thank you to all your advices, I finally succeeded to unfroze that screw. I tryed to move the shuttle race accordingly to manual but the shuttle itself was then rubbing on the other side of the race so I revert to initial position... to realized that I messed timing up and had to resync everything... I then decided to see if I could move the feeddog, and messed up everything again... It took me another hour to understand what to do and fix that issue So I am now back to the start point. I am considering doing the procedure below as suggested by @friquant but i am messing up so much that I feel a bit scared... My situation is number II so it won't be an easy fix procedure

Yes, allen wrench and nothing stronger than wd40 It's the red circle, the blue ones are ok. I am supposed to free all three in order to move the all shuttle part according to engineer's manual As shown here :

@AlZilla working on it 😅 @friquant I have the chapman set, it cost me much more here in Europe but it's so far one of my best buy, no regrets ! The screw is hexa type and above in size of the ones included in the set. I put some wd40 yesterday, I'll try again today...

Hi, well I guess I will have to make discussed adjustments first, and then post feedback here once done... So far my issue is a reluctant screw that I am still trying to free in order to proceed I also post extra pics as requested by @Constabulary and @AlZilla
