Amal 900 Series, MK1 Concentric Carburetor Modification

Please note that due to lack of volume and the retirement of our primary machinist, we are temporarily suspending the Amal Concentric Rebore.

This does not affect the Nortec, Norton gearbox seal or tach drive seal operations.



Object:  To recover worn and warped carburetor bodies and to return body-to-slide clearance to original specifications, thereby allowing precision control of the idle settings.

Procedure:  This process does not involve a sleeve!   The used carburetor body is bored to accept an oversize chrome plated brass slide, the mounting flange is milled flat, and the o-ring groove is re-cut as necessary.  Because of the design of the slide, the original choke slide cannot be used.  All other original parts are retained.
