The CA125M-10 similar to the CA125M mono-fuel mixer except that it has been modified with a vacuum lift for the gas valve. A CA125M-10 mixer can be fitted to the air horn of a carburetor with the now obsolete AA3-4 adapter, which mated to CA300A adapters. However, a machinist could easily build an adapter like the AA3-4. The CA125M-10 mixer can also be fitted to a gasoline carburetor's air horn with the low-profile Unidapt system using the A1-53 adapter.
