I always have such incredible luck with brass parts. My screwdriver slipped and I broke my pilot jet. Should I be concerned? I can always grab a vice grips and snug it up. If it will affect the jet at all (don't see why it would) I can always buy a new one, but only if I have to.

 

unless it's clogged nothing will happen... one of the ones on my shadow are like hat and it still runs like a honda ^_^... and when i took apart the carbs on my 95 f3 there was one already broken... issue was it was clogged solid so i had to easyout it
