1931 Carburetor Information

RJH-08

1929
The RJH08-125S Carburetor was used on the first five months production of six-cylinder models (1929).  This model has a small, and short, accelerator pump.  When replacing this on an International Model (1929) the RJH-08-136S model should be used.  The 136S has an accelerator pump which is small in diameter, but longer - reaching almost to the bottom of the bowl.  (The 136S should be used only on International (1929) Model motors and should not be installed on Universal (1930) Model motors.)

1930-1931
The RJH08-150S differs from the RJH08-136S in jet sizes and will not give satisfactory performance on the International (1929) model due to changes in valve design and the intake manifold.  (j)
