Uh, TeriAnn, you mis-read his message. He has needle-type valves, and
wanted to know about GrossJets.
Personally, I don't think I've heard of anyone other than you having
problems with GrossJets. I installed some in my TR6 (Z-S carbs) 3 years ago,
and have had no problems.
Perhaps, as you said, you got a bum one, or maybe you got a load of
bad fuel or had a hole in your fuel filter that let something nasty into
your jet/carb, or maybe just gasoline "varnish"/gum built up.
