My Blasters been running like crap,Constantly loading up if i'm not all over it.So reading all the posts that I have, I thought it was the temp change and jetting.Long story short,my reed cage has a gouge in the tip under a reed.That explains the loading up.v force delta 3 time.Anyway,When I took the carb out, I noticed the needle pin is blue,and there is wear on the pin down to the Aluminum,through the blue color.I have never seen a blue needle pin..Anyone have any knowledge about this?? Obviously I need to rebuild,but what does the blue needle represent? I also noticed that the top overflow on the inside of the carb[on the outside of the carb,kicker side] has been blocked off. Any reasons??
