So I'm thinking my needles are working loose, which is why my tuning is being such a pain. After all my tuning, I checked my needle settings last night, and the low is at 1 3/4 still. I know I have leaned it out more than that. I'm going to double check when I go out this weekend. Does anybody have any tricks for tightening up the needles? Can I put a little loctite on the threads and let it dry out prior to screwing it back in, or can I just put a dab with the needle still installed to hold it? Any help would be appreciated, thanks!
