Bob,
I have seen this (and even experienced it myself). In my case it turned
out that the needles I was using were too rich for the application. If
all else is in top form, you might see what needles you have and consult
Joe Curto about possibility changing to a leaner needle set. He might
also offer some pointers on the problem.
Regards,
Joe Curry
