Robert,
Grose jets have lots of little holes where the "ball valve" moves up and
down. These holes are great for collecting little particles of whatever
and keeping the ball from seating completely which causes the carb to flood.
I've taken out the two sets of grose jets I have and put the old ones bad
in. My experience has been the old ones have fewer problems.
