First thing I did was get it CLEAN. Everywhere, but especially around the extractor. Didn't help. I'm really hoping the new extractor solves it. Maybe I should ping Redneck before I do anything else?
When you take the extractor out, you might want to do it with the bolt inside a jumbo size ziplock bag. The spring is small and the first time that I replace an extractor the spring disappeared and has not been seen since.
