Murray M2550: Two-Stroke Straight-Shaft Trimmer and Briggs and Stratton Brand Context
The Murray M2550 uses a two-stroke engine requiring a premixed fuel and oil ratio as specified in the owner’s manual. Murray is a Briggs and Stratton brand, meaning both Murray trimmer components and equivalent Briggs and Stratton parts are catalogued together. Carburetor varnish from ethanol-blend fuel during off-season storage is the leading cause of hard starting and stalling at the start of the trimming season. The string trimmer repair help section covers M2550 carburetor service and trimmer head line winding.
Most Replaced Parts on the Murray M2550
Carburetor for the Murray M2550
The diaphragm carburetor is susceptible to varnish deposits from ethanol-blend fuel during off-season storage. Cleaning restores function in most cases. When the diaphragm has hardened or cracked, carburetor replacement is the most reliable solution.
Spark Plug for the M2550
Annual spark plug replacement maintains reliable starting. Always use the fuel mixture ratio specified in the M2550 owner’s manual.
Air Filter for the Murray M2550
Replace the air filter at the start of each trimming season. A clogged filter causes the engine to run rich and lose cutting power at full throttle.
Trimmer Head for the M2550
The bump-feed trimmer head advances line when tapped against the ground. Replace the head when the bump knob mechanism no longer advances line reliably.

Murray M2550 String Trimmer Parts FAQ
What is the Murray M2550 and what engine does it use?
The Murray M2550 is a straight-shaft two-stroke gas string trimmer from Murray. Murray is a Briggs and Stratton brand, and many Murray trimmer engine components are catalogued alongside equivalent Briggs and Stratton parts.
Why does my Murray M2550 not start after off-season storage?
Hard starting after storage is almost always caused by carburetor varnish from ethanol-blend fuel in the float bowl during warm months. Drain the float bowl before off-season storage. Replace the fuel filter and clean the carburetor before ordering a replacement.
How do I reload the trimmer head on the Murray M2550?
Press the retainer tabs on the bump knob to remove the spool. Wind new line in the direction shown by the arrow on the spool, thread the ends through the eyelets on the head housing, and snap the spool back into place.
Why does my Murray M2550 stall under trimming load?
A trimmer that starts but stalls under load most commonly has a clogged high-speed needle jet in the carburetor, a clogged fuel filter, or a cracked fuel line creating an air leak. Replace the fuel filter first before disassembling the carburetor.
