I bought a few sets of them, but never used their needles. The jets are 110, the bowl gaskets are a bit "soft" and need to be placed carefully so they don't move out of place. mixture screws seemed OK, and their float valves did not leak (but looked less "refined" than OEM)
If your hard parts are OK, and the carbs do not drip fuel, I would just buy the bowl gaskets.
