In recent years, the replacement floats for SU carbs were all plastic. with no method of adjusting the float valve operation. To make matters worse, many suppliers stocked only "offshore" versions that leaked and did not last. This made setting up HS series carbs challenging. Now Seven offers a superior product that overcomes the previous difficulties. Suitable for HS2 or HS4 carbs. Made in the U.K.
The new adjustable height StayUp® float is resistant to modern ethanol based fuels and has a military spec closed cell construction making it puncture proof. The ability to adjust the float arm allows for quick and easy minor alterations to float levels where required. The material specified was used by the S.U Carburetter Company for military installations in the 1980s, where a guaranteed fail safe operation was critical.
The ease of adjustment is enough reason to select these floats compared to the modern OEM floats. The arm can be easily bent to achieve the recommended action of the needle valve.
This is the float we recommend for any street-driven or performance Mini. We suggest ordering a new AUC1152 pivot pin for each float.
