A carburetor repair kit gives your Murray mower a second life without the cost of a full replacement. These kits include gaskets, seals, jets, floats, and needle valves—all the internal parts that wear out and cause rough running, hesitation, or stalling. Repair Clinic's genuine OEM kits are formulated specifically for Murray carburetors to restore fuel atomization and engine response.

OEM Murray kits include float bowl gaskets, inlet needle and seat, main and idle jets, o-rings, seals, and often a new float if the original is waterlogged. Some factory-certified kits add carburetor cleaner and a rebuild guide specific to your carburetor model. Always check the kit contents against your parts diagram to ensure nothing is missing.

However, if you need to clean internal passages or replace the main jet, complete removal is faster and safer. Lay down cardboard to catch small springs and screws during disassembly.

Yes—fuel leaks and flooding are usually caused by a worn float needle or degraded float bowl gasket. A repair kit provides both replacement parts. However, if the float itself is cracked or the bowl has a hole, you'll need to order those parts separately for a complete fix.

Murray usually places the model number on a metal plate or sticker on the mower deck or rear frame. Check around the blade deck first, then look on the engine housing if you do not see it there.

Enter that number in the model number search to pull up the parts matched to your unit. Because the model number identifies the entire Murray lawn mower, it narrows the full catalog to compatible parts across every repair category, not just carburetor parts. You order with confidence knowing the fit is right.
