i have an old goodyear curved needle that i bought off a fella and it has (like most others i'm sure) all sorts of landis parts, usmc parts...who knows....i have broken the needle guide and need a new one. my supplier sent me a landis #2 guide, but that doesn't seem to line the needle up right with the clamp hole. i've busted my hump tryin' to figure this one out and everyone wants parts #'s for the machine, but this thing is older than dirt and there aren't any. the old guide had a L0 on it, but no one seems to know what that's all about. any help? also, is there any reason that the needle guide would just break in the middle of nothin'? i think my tensioner on the bottom had gotten a little loose and the arm came down and got into a bind when it broke, but that's just speculation....now i need a new needle guide that fits so i can be back in business. thanks in advance.
