Homelite UT33600: Two-Stroke Straight-Shaft Trimmer Service
The Homelite UT33600 uses a two-stroke engine requiring a premixed fuel and oil ratio as specified in the owner’s manual. 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 UT33600 carburetor service, fuel filter replacement, and trimmer head line winding.
Most Replaced Parts on the Homelite UT33600
Carburetor for the Homelite UT33600
The UT33600 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 UT33600
Annual spark plug replacement maintains reliable starting. Always use the fuel mixture ratio specified in the UT33600 owner’s manual.
Air Filter for the Homelite UT33600
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 UT33600
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 or the head housing is cracked.

Homelite UT33600 String Trimmer Parts FAQ
What is the Homelite UT33600 and what type of trimmer is it?
The Homelite UT33600 is a straight-shaft two-stroke gas string trimmer from Homelite. The UT33600 model code identifies the specific carburetor and fuel system configuration within Homelite’s UT trimmer series.
Why does my Homelite UT33600 not start after off-season storage?
Hard starting after storage is almost always caused by carburetor varnish from ethanol-blend fuel sitting in the float bowl during warm months. Drain the float bowl before off-season storage to prevent this. Replace the fuel filter and clean the carburetor before ordering a replacement.
How do I reload the trimmer head on the Homelite UT33600?
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 Homelite UT33600 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.
