Dolmar MS-22 C: Two-Stroke Straight-Shaft Trimmer and Makita Brand Context
The Dolmar MS-22 C uses a two-stroke engine requiring a premixed fuel and oil ratio as specified in the owner’s manual. Dolmar is a Makita-affiliated brand, and many trimmer components share design lineage with equivalent Makita models. Carburetor varnish from ethanol-blend fuel during off-season storage is the leading cause of hard starting and power loss at the start of the trimming season. The string trimmer repair help section covers MS-22 C carburetor service and trimmer head line winding.
Most Replaced Parts on the Dolmar MS-22 C
Carburetor for the Dolmar MS-22 C
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 MS-22 C
Annual spark plug replacement maintains reliable starting. Always use the fuel mixture ratio specified in the owner’s manual.
Air Filter for the Dolmar MS-22 C
Replace the air filter at the start of each trimming season. A clogged filter causes the engine to run rich and lose cutting power.
Trimmer Head for the MS-22 C
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.

Dolmar MS-22 C String Trimmer Parts FAQ
What is the Dolmar MS-22 C and what type of trimmer is it?
The Dolmar MS-22 C is a straight-shaft two-stroke gas string trimmer from Dolmar. Dolmar is a Makita-affiliated brand, and many Dolmar trimmer components share design lineage with equivalent Makita string trimmer models. The C designation identifies a specific handle or starting system configuration within the MS-22 series.
Why does my Dolmar MS-22 C not start after off-season storage?
Hard starting after storage is most commonly caused by carburetor varnish from ethanol-blend fuel sitting in the float bowl during warm months. Drain the float bowl before off-season storage. Replace the in-tank fuel filter and clean the carburetor before ordering a replacement.
How do I reload the trimmer head on the Dolmar MS-22 C?
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 Dolmar MS-22 C lose power under trimming load?
Power loss under load most commonly indicates a clogged air filter, a partially blocked carburetor main jet from ethanol varnish, or a clogged fuel filter restricting fuel delivery. Replace the air filter and fuel filter before disassembling the carburetor.
