You have to use a .023 tip,and your tension might be too tight on the spool.If the wire is rusty,spray it with WD 40 clothespin and a piece of a scotch brite pad,spray it good with WD40,clip it over the wire where it feeds into the liner past the rollers.If its real rusty you might want to take the top layer off.You might have to get a new liner just to run .023 because the .035 might have a groove worn in it and the .023 might be wiggling as at goes through causing it to bind.You might have to get different rollers..023 doesnt push as easy as .035.It takes a little finer tune on everything.If you didnt change the tip,thats the best bet as to the problem,also you need to cut the heat down from the .035,and the wire speed too.It might not be adjusted close enough so that when you start welding you get instant birdnest.With .023 you just dont have as wide of a range that it runs good in as with .035.Also you want to snip the end of the wire before you weld.Its more critical to do this with .023 than .035.I dont know about a Lincoln,but with mine I set the wire speed at about 1/3 less,and 1 heat range lower,just to start with and that seems to work.Once you get it running you can fine tune the feed,but most likely its too high.Also want to make sure you have a good ground,sometimes I just weld the ground to what I am welding.If none of that works explain better what its doing.It might take a while for me to see it,but if it happens with a mig it probobly has happened to me before as I have worn a couple of industrial Hobarts out in my life,and other than the electrical part of it,I might be able to tell you what to try.You dont say,but if the .023 spool is smaller than the .035 spool you were using,you can bet your spool tension is too tight.Maybe you had a 10lb .035 and a 2lb .023?
