Question on a choke

[slave601]

Over time can a choke "wear" out? I had an old jellyhead I've had for years an put it in my new supermag and the patterns were good. Put in a brand new jellyhead an not the maximum jus regular and the patterns were a lil better. Got me to thinking.

Few things can happen.   One thing It can wear out. (takes a lot)  Now one big thing is that it can build plastic or lead in it.   Another thing is they may have changed the layout of the choke.
