Ok so a bit of back story, got a import ATI auto in a trade that has the worst stuck tube I've ever seen. I have a 100 straight tube removal set I built and this got the tube unscrewed. However this tube is so enlarged even after it's completely unscrewed the tube is still firmly held in the barrel. Any ideas other than pinning a plug in the choke so as to coerce it out with a slide hammer or a brass rod from the inside? I've soaked it in penetrating oil, I've frozen it, I've tried the lathe chuck.
This is the poster child of what not to do to a screw in choke, no lube, never removed for cleaning, goose gun that got a solid diet of 3.5 high speed steel for 3 seasons straight.
