Craftsman 358792010 trimmer Parts

To replace trimmer line on your Craftsman gas line trimmer model 358792010, remove the old line, clean the trimmer head, then install new Craftsman replacement line so both ends feed evenly and end up the same length. Follow the exact head style steps in the 358792010 owner's manual.

• Disconnect the spark plug boot before maintenance.
• Work on a cool engine and keep the trimmer stable on a flat surface.
• Wear eye protection, gloves, and hearing protection.
• Use only trimmer line; never use wire, rope, or string.
• Keep the debris shield installed and secure.

• Remove any remaining line.
• Remove the line glide plate (it is held in place by the cutting line).
• Clean the entire trimmer head surface.
• Reinstall the line glide plate.
• Insert both ends of the new line through the correct holes in the side of the head.
• Pull both lines so they sit against the hub and extend fully through the positioning tunnels.
• Confirm both ends are the same length.

• Remove any remaining line and clean the head.
• Use 15 ft (4.5 m) of 0.095 in (2.4 mm) Craftsman line.
• Align the arrows on the tap button with the line exit holes.
• Bend the line at the midpoint and feed both ends through the center holes in the tap button.
• Pull both ends evenly so the line seats against the tap button and exits equally.
• Rewind by turning the tap button in the direction shown on the spool.

Most cutting problems come from using the wrong diameter or type of line.

Correct line size and even winding reduce tangles, improve cutting power, and prevent the line from retreating into the head during use. It also helps protect the trimmer head parts from premature wear.

For the Craftsman 358792010 gas line trimmer, we use Craftsman replacement trimmer line; for a bump-feed head, the operator instructions specify 0.095 inch (2.4 mm) diameter Craftsman line. For fixed-line heads, the manual directs you to choose the Craftsman line size best suited to the job. See the 358792010 operator's manual for the exact line type and replacement steps.

The manual calls out Craftsman replacement line and gives common use cases by color/part reference:

• 0.095 in (2.4 mm) Craftsman line for bump-feed heads (specified)
• Red line (#71-85908) for grass and small weeds
• Black line (#71-85909) for larger weeds and light brush
• Do not use wire, rope, string, or any blade-style attachments

Use this as a fast check before you order line.

Using the correct diameter and a recommended line material helps the trimmer head feed properly, reduces vibration, and prevents premature wear to the head and shield. Using wire or rope is unsafe and can damage the trimmer.

If the line keeps retreating or will not advance:

• Clean the trimmer head and line path before reloading
• Make sure the line is even length on both sides after loading
• Confirm the line is routed through the correct exit holes/tunnels
• Replace old, brittle line (especially if it was stored in heat)

For the Craftsman 358792010 gas line trimmer, the fuel line size most commonly used is 9/64 inch outside diameter (OD) with 0.080 inch inside diameter (ID). Confirm the exact routing and connections in the 358792010 owner's manual before cutting and installing new line.

Fuel line is sized by ID (what fits over the tank fitting or carburetor nipple) and OD (what fits through grommets and passages). Before you buy or cut line, we recommend:

• Measure the old line’s ID and OD with calipers (or compare to a drill bit shank)
• Check that the line seats fully on fittings without forcing it
• Verify it passes through the tank opening or grommet without kinking
• Replace any hardened, cracked, or swollen line at the same time
• Inspect related fuel-system parts for leaks before use (per the manual)

If the original line is missing, these are the most common small-engine trimmer sizes to compare:

A fuel line problem often shows up as hard starting, surging, or fuel smell. While servicing the line, also check:

• Fuel isolator 530059780 for cracking or deterioration
• Fuel cap seal and tank venting (a plugged vent can starve fuel)
• Carburetor mounting surfaces and gaskets
• Primer bulb and fuel filter (if equipped)

Using the correct fuel line size prevents air leaks and fuel leaks, which protects the carburetor’s fuel delivery and helps the engine start and run consistently.

If your Craftsman 358792010 gas line trimmer is flooded, clear the excess fuel by opening airflow, drying the spark plug area, and then restarting with the throttle held open so the engine can pull in more air and purge the rich fuel mix. Use the starting steps in the 358792010 owner's manual.

• Move the unit outdoors; never run a gas trimmer in an enclosed area.
• Set the ON/STOP switch to ON.
• Remove the air filter cover and air filter briefly to increase airflow (reinstall after it starts).
• Remove the spark plug, dry it, and let the cylinder air out for a few minutes.
• Reinstall the spark plug, then pull-start with the throttle held wide open (do not prime).
• Once it fires, feather the throttle and let it warm up; then reinstall the air filter.

Flooding often points to a fuel or ignition issue. Check these common items:

• Spark plug: fouled plug will not ignite a rich mixture.
• Air filter: clogged filter makes the mixture too rich.
• Fuel cap venting: a bad cap can cause fuel delivery problems; consider the lawn mower fuel cap 545073101 if your cap is cracked or will not vent.
• Fuel system leaks or soft lines: inspect for wet spots and loose fittings; a damaged fitting can be replaced with the ayp chainsaw fuel line fitting 530023877.
• Idle speed set too low or too high: after it starts, set idle so the trimmer head does not spin at idle (the manual describes the idle speed screw direction).

A flooded 2-cycle trimmer has too much fuel and not enough air in the cylinder, so the spark cannot light the mixture. Clearing it correctly prevents plug fouling, reduces pull-start strain, and gets you back to trimming safely.

When your Craftsman trimmer model 358792010 dies as you squeeze the throttle, the engine is usually going lean or getting too much fuel under load. The most common fixes are cleaning the air filter area, refreshing fuel, and checking ignition and fuel delivery basics using the steps in the 358792010 owner's manual.

• Use fresh fuel mix and empty old fuel from the tank; stale fuel causes bogging and stalling on acceleration.
• Inspect the air intake and filter area; a restricted air path can make the mixture too rich and stall.
• Check the fuel cap vent; a plugged vent can starve fuel as RPM increases.
• Inspect fuel lines and fittings for cracks, soft spots, or leaks.
• Check the spark plug condition and gap; weak spark shows up most when you open the throttle.

If the basics above do not solve it, these model-related parts are common culprits when a trimmer stalls on throttle:

Model-specific parts we often see involved:

• Fuel isolator 530059780 (helps isolate and route fuel components; damage can contribute to fuel delivery issues)
• Line trimmer carburetor gasket 545008086 (air leaks at the carb can cause a lean condition on acceleration)
• Lawn mower fuel cap 545073101 (a venting issue can mimic fuel starvation)

We follow the same safety guidance used in the manual:

• Disconnect the spark plug before maintenance (except carburetor adjustments).
• Work outdoors when handling fuel; wipe up spills before starting.
• Keep bystanders at least 50 feet away during operation and adjustments.

A trimmer that stalls when you “give it gas” is telling you the engine cannot maintain the correct air-fuel-spark balance under load. Fixing the root cause prevents hard starting, poor cutting power, and repeated plug fouling.

The Craftsman 358792010 uses 0.095 inch (2.4 mm) diameter cutting line for the bump-feed trimmer head; a full reload uses 15 ft (4.5 m) of line. For the exact routing and winding steps, follow the 358792010 operator’s manual.

Use these specs when you are replacing the cutting line on this model:

• Line diameter: 0.095 in (2.4 mm)
• Reload length (bump-feed head): 15 ft (4.5 m)
• Use Craftsman replacement line
• Never use wire, rope, or string

The manual also calls out common line choices by color:

• Red line: grass and small weeds
• Black line: larger weeds and light brush
• Pick the line that matches what you cut most often

Using the specified diameter helps the trimmer feed smoothly and prevents spool jams. Oversized line binds and strains the head; undersized line breaks faster and reduces cutting performance.

• Clean the trimmer head before installing new line
• Wind the line evenly so it does not cross over itself
• Make sure both ends exit the head at the same length
• Replace worn head components if the line keeps retreating
