My initial good experience with Grose jets was in '79 when I bought my first
B and those jets are still in the car and working fine 150K later.  My bad
experience with them was in '85 when I bought my first 1100.  I had the same
experience you did with incessant sticking and I haven't used Grose jets 
since.  At the time, I compared the two sets of jets and the little balls 
were actually different sizes.  I vaguely remember the non-sealing balls 
being larger in the newer jets.  It made sense to me that little particles 
would make these larger balls stick against the side of the cage.

However, you got good Grose jets a year ago and now the newer ones are bad
again.  It sounds like the company is either switching back and forth between 
vendors or their quality control isn't very good.  I wonder if they even know 
that large numbers of their product are defective.
