Genuine Mercury/Tillotson brass carburetor idle restriction tube for all 1958-66 Mark 55H - 58 - 58A - 78 - 78A and all 1960-66 Merc 400 - 450 - 500 - 650 - 700 - 800. This tube has a very small orifice that is easily blocked by debris or decomposing fuel. Once the fuel breaks down into "varnish", its extremely difficult to remove. If your motor runs fine at high speed but won't idle, this tube could be the culprit. Includes copper gasket (1) required per carburetor + + + + Specify carburetor when ordering
