I have 86 Savage and I've had nothing but trouble with my pilot jet backing out and flooding my engine. I've tried a few thing but I'm the end I just bought a newer carb. I got my hands on an 07 carb thinking all my problems and solved but it still happening. I do only city riding doing 45-50 top and not for long. I do last on the throttle kind of hard though and I think that vibration is what backs it out. Has anyone else had this problem before?

Did you transfer jets from the old carb? I f you did ,perhaps the problem is the pilot jet not the carb body.

I don't really know, but it may be possible ,the carb body should be harder metal, than the brass jet . I 'd try a new pilot jet , in the new carb, for what it costs .
