greetings....i am new to rotary forum, and hope im posting in the right place (gulp)

i recently bought a ttech setup...needle cartridges/tube/needle bar adapter...

it seems that the tips dont really 'snug up' into the tube

??

i tried 5 rsl's and 7 mags.....they both barely stay in...the slightest touch makes em wiggle...

i wrote ttech..they assured me that theyve never had anyone complain....

maybe i just got a bunk set?

help me rotary forumaniums
