The cost of these Grose Jets are extremly high $15.95 compared to our 2-piece $6.00 needle and seat sold in the shopping cart and included in our rebuild kits. We are stocking these as we do get calls on occasion. These will replace your standard 2- piece needle and seat . Mr. Grose had the bright idea of completely re-designing the 2-piece needle and seat. His idea was to use a ball bearing that would constantly present a new surface to the seat and therefore provide a consistent metering of fuel. A large ball was used as the surface that the float would act against while a smaller ball would come in contact with the seat.
