hello forum.. i just ordered a bag of needle runners from kingpin and cant seem to get them to work..either its to big and causes friction in which i need to higher the voltage or it runs perfect but the needle sits (or is pushed i might say) against the top of the tube tip.. ive seen thier website and still cant figure this out...just throwing this out thereseeing if anyone would know a little trick to these...if not fuk it..worst case ..just stick to the old trusty rubberband....peace
