Craftsman 358795190 trimmer Parts

For the Craftsman 358795190 gas line trimmer, we do not recommend using .095-inch line; the 358795190 owner's manual specifies using only 0.080-inch (2 mm) diameter Craftsman brand line. Using thicker line can overload the trimmer head and engine, causing poor performance and premature wear.

What to use instead (best choice for this model)

Use the line size and type the trimmer was designed to spin at full RPM.

• Use 0.080-inch (2 mm) diameter line
• Use nylon trimmer line only (no wire, rope, or string)
• Keep the cutting line at the proper length so the head does not bog down
• Replace trimmer head parts if they are chipped, cracked, or broken

If you want “stronger” cutting without thicker line

Strength is not only diameter; line shape and how you run the tool matter more on a smaller gas trimmer.

Practical upgrades that stay within spec

• Choose a premium 0.080-inch line (often lasts longer than bargain line)
• Use less than full throttle for light trimming to reduce line wear
• Use full throttle for mowing or sweeping so the line cuts cleanly
• Trim with the tip of the line (do not force the line into heavy growth)

Quick comparison: .080 vs .095 on this trimmer

Item	0.080-inch line (recommended)	0.095-inch line (not recommended)
Fit in head	Correct	Often binds or feeds poorly
Engine load	Normal	Higher load, more bogging
Cutting feel	Clean at proper RPM	Can feel “strong” but slows head
Wear risk	Normal	Higher wear on head/engine

Why it matters

This Craftsman trimmer is designed around a specific line diameter. Staying with 0.080-inch line helps the trimmer head feed correctly, keeps RPM up for cleaner cuts, and reduces stress on the clutch, drive components, and engine.

For a Craftsman 358795190 2-cycle trimmer, the exact fuel line inside diameter and outside diameter are listed in the parts breakdown and specs in the owner's manual. Most small 2-cycle Craftsman handheld engines use two different fuel lines (feed and return) sized to seal tightly in the tank grommet and carburetor fittings.

How to choose the correct fuel line size

We match fuel line by function and fit, not just “one size.” Use these checks:

• Identify whether you need the fuel supply line (tank to carburetor) or fuel return line (carburetor back to tank)
• Measure the old line’s inside diameter (ID) and outside diameter (OD) if you still have a piece
• Confirm the line passes through the tank opening or grommet snugly (no seepage)
• Make sure the line fits the carburetor nipples without stretching or cracking
• Replace the fuel filter at the same time if it is restricted or falling apart

If you’re replacing the return line specifically, the parts list for this model includes a dedicated return line: lawn & garden equipment engine fuel return line 530069599.

Quick symptoms that point to the wrong fuel line size

What you notice	Most likely issue	What to do
Fuel leaks at tank opening	OD too small or hardened line	Use correct OD line and re-seat through tank opening
Line won’t stay on carb fitting	ID too large	Use smaller ID line for a tight push-on fit
Engine starts then dies	Air leak or restricted filter	Check line cracks, replace filter, verify routing
Primer will not fill	Supply/return swapped or air leak	Re-route lines per diagram in the manual

Why it matters

A 2-cycle trimmer like the Craftsman 358795190 depends on an airtight fuel path. A slightly wrong ID/OD can pull air, cause hard starting, stalling, or fuel leaks, and it can also prevent proper priming.

Ordering the right parts

We recommend using the model-specific diagrams to select the correct fuel system parts for Craftsman 358795190, then ordering from the parts list for this model or searching by model number on Sears PartsDirect.

To replace the cutting line on your Craftsman 358795190 gas line trimmer, we install new 0.080 inch (2 mm) round trimmer line onto the spool so it lays evenly with no overlaps; that prevents tangles and helps the head feed line correctly. For the exact head style and spool routing, follow the steps in the owner's manual.

Before you start (safety and the right line)

• Turn the ON/OFF switch to OFF and let the engine cool.
• Disconnect the spark plug before maintenance.
• Use only 0.080 inch (2 mm) diameter round line; do not use wire, rope, or string.
• Keep the debris shield installed; it sets the cutting path length.
• Work on a clean bench so the spring and spool parts do not get lost.

Replacing the line (typical bump head style)

1. Remove the trimmer head cover (tabs or screws, depending on the head).
2. Lift out the spool and note how the old line was routed.
3. Cut two equal lengths of 0.080 inch line (many heads use two pieces).
4. Anchor each line end in the spool hole/slot, then wind in the direction shown on the spool.
5. Wind tightly and evenly with no crossing or overlapping.
6. Feed the line ends through the eyelets, reinstall the spool and spring (if used), then snap the cover back on.
7. Pull both line ends to confirm the spool turns freely and the line is not jammed.

What “no overlapping” looks like

Spool winding	What happens	Result
Even, side-by-side wraps	Line pays out smoothly	Proper feed and cutting
Crossed or overlapped wraps	Line binds on the spool	Poor feed, tangles, breakage

If the line will not advance after reloading

• Confirm you used 0.080 inch (2 mm) round line.
• Rewind the spool tighter; loose wraps “weld” and stick.
• Check the head for cracked or worn parts; replace damaged head components.
• Do not tap the head on the ground to advance line; this can break parts.

Why it matters

Correct line size and neat winding keep the cutting head feeding automatically and reduce vibration, noise, and premature line wear. It also helps protect the trimmer head from damage caused by jams.

If you need replacement components while servicing the head, we stock common ignition and starting parts for this model, such as the lawn & garden equipment kill switch 530069572. You can also search by model number on Sears PartsDirect if you are ordering additional parts.

If your Craftsman 358795190 gas line trimmer will not start, the most common causes are incorrect or stale 40:1 fuel mix, a choke setting that is not used correctly during cold starts, or restricted airflow and fuel flow. Start by confirming fresh fuel and the correct choke sequence in the owner's manual.

Quick checks that fix most no-start problems

• Mix fresh fuel at 40:1 (8.2 oz 2-cycle air-cooled oil per 1 gallon unleaded gas); shake the container to fully mix.
• Use the choke correctly: FULL CHOKE to start, move to HALF CHOKE after the engine attempts to start, then OFF CHOKE once it runs.
• Move at least 10 feet away from the fueling spot before starting.
• Clean the air filter (a clogged filter can flood the engine by reducing airflow).
• Replace old fuel; do not use last-season gas.
• Check the stop switch wiring; a shorted kill switch can prevent spark.

Fuel and choke: the most common root cause

This model is designed for unleaded gasoline mixed with 2-cycle air-cooled oil at 40:1. If the mix is wrong (too much oil, too little oil, or old fuel), the engine can be hard to start or not start at all.

Choke positions (what to do)

Engine condition	Choke position	What you should see
Cold engine	FULL CHOKE	Engine “pops” or attempts to start
After it pops	HALF CHOKE	Engine starts and runs briefly
Once running	OFF CHOKE	Engine keeps running without loading up

Electrical no-start: kill switch and wiring

If fuel and choke are correct and it still will not fire, the stop circuit is a strong next suspect.

• Inspect the switch and leads for pinched insulation, loose connectors, or corrosion.
• If the switch feels loose or intermittent, replace it with the model-matched lawn & garden equipment kill switch 530069572.
• If the lead wire is damaged, replace the harness with the lawn & garden equipment lead wire assembly 530047278.

Why it matters

A 2-cycle trimmer that is fed the wrong fuel mix or started with the wrong choke sequence can flood quickly, foul the spark plug, and become difficult to restart. Fixing fuel quality and the stop circuit first prevents unnecessary carburetor adjustments and repeat no-starts.

For the Craftsman 358795190 gas line trimmer, use the trimmer line size specified for the cutting head on your unit. Many Craftsman bump-feed heads run 0.095 in. line, while some fixed-line heads use 0.110 in.; confirm the exact size in the 358795190 owner's manual.

How to choose the right line for your 358795190

Use these checks to match the line to the trimmer head and avoid feed problems:

• Read the line size molded or printed on the trimmer head (often near the spool cap)
• Match the line diameter exactly (common sizes are 0.095 in. and 0.110 in.)
• Use nylon trimmer line (round or twisted styles work well for general trimming)
• Cut two equal lengths if your head uses fixed-line inserts
• Wind the spool in the direction shown on the head to prevent tangles

What to avoid

Wrong line size or material causes poor cutting and can damage the head.

• Do not use wire, cable, rope, or string
• Do not force oversized line into a bump head
• Do not mix different diameters on the same spool

Quick line-size guide

Head style (common)	Typical line diameter	What happens if the line is wrong
Bump-feed spool head	0.095 in.	Jams, won’t feed, engine bogs
Fixed-line head	0.110 in.	Line won’t fit or breaks too fast

Why it matters

The trimmer head, clutch load, and cutting performance are designed around a specific line diameter. Using the correct size improves feed reliability, reduces vibration, and helps prevent premature wear.
