O.S.SPEED R21 SHIMO EDITION 2 About the initial position of the carburetor

Thank you for your continued support of the OS SPEED engine products.
Early production batch of O.S.SPEED R21 SHIMO EDITION 2, depending on the climate and fuel, the initial carburetor setting position of the metering needle might be set to too lean.
As shown in the picture below, please readjust the metering needle to open about 0.5 mm (about 1 turn) come out from the flush position.
We apologize for the inconvenience.
