On the Craftsman high wheel line trimmer model 917773754, replace the trimmer line by installing two equal-length pieces of .155-inch line, each cut to 18-3/4 inches, into the carrier plate and seating them under the retainer clips. Follow the steps in the 917773754 owner's manual.

Step-by-step: replace the trimmer line

• Disconnect the spark plug wire and keep it away from the spark plug.
• Remove the worn trimmer line from the carrier plate.
• Cut new trimmer line to 18-3/4 inches (use .155-inch diameter line).
• Fold one piece of line in half.
• Insert the folded end through the carrier plate opening to the back side of the retainer clip.
• Pull the line outward until it is fully seated under the retainer clip.
• Repeat for the other side, then reconnect the spark plug wire.

Getting the length right (prevents vibration)

After installing new line, we check that both cutting ends are the same length and do not vary by more than 1 inch. Uneven line length makes the trimmer head unbalanced and can cause excessive vibration.

Spec	What to use on model 917773754	Why it matters
Line diameter	.155 inch	Correct fit and retention
Line length (each piece)	18-3/4 inches	Proper cutting reach and balance
Max length difference	1 inch	Reduces vibration

If the head will not retain the line

These checks fix most “line won’t stay in” problems:

• Reinstall the line so it is fully seated under the retainer clip.
• Replace line that is worn to less than half its original length.
• Use only .155-inch line (wire, rope, or smaller line can slip or fail).
• Inspect the carrier plate for damage; replace it if the retainer area is broken.

If you need the carrier plate, match it to the correct part for this model, such as the line trimmer carrier plate 594935003 when it applies to your cutting head setup.

Why it matters

Correct line size and equal lengths help the trimmer cut cleanly, reduce vibration, and prevent premature wear on the cutting head (including the ball at the bottom of the head).

For the Craftsman 917773754 high wheel line trimmer, use fresh unleaded regular gasoline and the engine oil specified in the 917773754 owner's manual. This model is a walk-behind trimmer that uses straight gas in the fuel tank and SAE 30 (above 32°F) or SAE 5W-30 (below 32°F) in the engine, not a 2-stroke gas/oil mix.

What to use (based on the manual)

The manual lists these specs for model 917773754:

• Gasoline type: Unleaded regular
• Fuel capacity: 1.25 quarts
• Engine oil type: API SF-SJ
• Oil viscosity: SAE 30 above 32°F; SAE 5W-30 below 32°F
• Oil capacity: 20 ounces

Quick temperature guide

Use the oil viscosity that matches your starting temperature:

Outdoor temperature	Oil to use
Above 32°F (0°C)	SAE 30
Below 32°F (0°C)	SAE 5W-30

Avoid this common mistake

Many handheld 25cc trimmers are 2-cycle and require mixing 2-stroke oil into gasoline. The Craftsman 917773754 is different; it has an engine oil fill and dipstick, so you:

• Put unleaded gas only in the fuel tank
• Add engine oil to the crankcase before starting
• Check oil level before each use

Why it matters

Using straight gas plus the correct SAE engine oil prevents hard starting, excessive smoke, and rapid engine wear. Mixing 2-stroke oil into the gas on this model can cause poor running and plug fouling.

Craftsman leaf blowers do not use one universal fuel-line size; the correct inside diameter and outside diameter depend on the exact blower model and how the line seals at the tank grommet and carburetor. Use your blower’s model-specific specs, or match the old line by measurement.

How we recommend choosing the correct fuel line

Use the old line as your template so the fittings seal and the engine gets steady fuel.

• Find the leaf blower model number on its housing label (not the trimmer model)
• Remove the old fuel line and note routing, filter position, and any return line
• Measure the old line’s inside diameter (ID) and outside diameter (OD) with a caliper
• Match the line to the tank grommet hole and carburetor nipple so it fits snugly
• Replace the in-tank fuel filter if it is loose, clogged, or brittle
• Use ethanol-resistant small-engine fuel tubing for better durability

Model note for Craftsman 917773754

The Craftsman 917773754 page is for a high wheel line trimmer, not a handheld leaf blower. The 917773754 owner’s manual covers fuel type and capacity (and other operating specs), but fuel-line dimensions are typically specific to the engine and fuel-tank setup.

Quick sizing guide (what to measure)

What you’re fitting	What must match	What happens if it’s wrong
Tank grommet pass-through	OD	Too small leaks air; too large will not seat
Carburetor fuel inlet	ID	Too small restricts fuel; too large can slip off
In-tank fuel filter barb	ID	Loose fit can fall off; tight fit can crack line

Why it matters

A fuel line that does not seal tightly pulls air into the fuel system; that causes hard starting, surging, and stalling. Correct sizing keeps the carburetor supplied and prevents leaks.
