Craftsman 316795861 gas trimmer & brush cutter Parts

To unflood a Craftsman gas trimmer & brush cutter model 316795861, we clear excess fuel from the cylinder and intake, then restart with the correct choke position. This usually fixes a no-start condition caused by too many primer pushes or repeated pulls with the choke on. See the starting procedure in the 316795861 owner's manual.

Quick unflood steps (safe, effective)

• Move the trimmer to a well-ventilated area and keep it away from sparks or flames.
• Set the switch to ON.
• Move the choke to RUN/OFF (choke open), not FULL CHOKE.
• Hold the throttle wide open (this lets more air in).
• Pull the starter rope 5 to 10 times until it tries to fire.
• If it starts, let it run 30 to 60 seconds to clear the remaining fuel.

If it still will not start

Check the spark plug (fastest confirmation)

• Remove the spark plug and inspect it.
• If it is wet with fuel, dry it completely and let the cylinder air out for 10 minutes.
• Reinstall and try the “Quick unflood steps” again.

Check airflow and fuel delivery

A flooded engine often happens alongside restricted airflow or a rich fuel condition.

• Clean or replace the air filter; a clogged filter makes the mixture too rich.
• If the trimmer only runs with the choke partly on, the carburetor may need service.

Symptom	Most common cause	What to do next
Strong fuel smell, plug wet	Flooded cylinder	Choke open, throttle wide open, pull 5 to 10 times
Starts then dies unless choked	Lean fuel delivery	Inspect fuel lines, consider carburetor service
Hard starting, bogging	Dirty air filter	Replace mtd line trimmer air filter 753-06417

Why it matters

Flooding washes fuel over the spark plug and reduces spark strength, so the engine cannot ignite the mixture. Clearing the extra fuel restores the correct air-fuel balance and prevents repeated pull-start strain.

To replace trimmer line on your Craftsman gas trimmer model 316795861, we install the correct diameter line into the trimmer head, wind it evenly (no overlaps), then feed the ends through the eyelets so the head can bump-feed smoothly. For head-specific steps, use the 316795861 owner's manual.

Quick steps (most bump-feed heads)

• Shut the engine off and let the muffler cool; remove the spark plug wire for safety.
• Clean grass and debris off the trimmer head so the spool can seat correctly.
• Remove the spool cap (usually press tabs or unscrew, depending on head style).
• Cut two equal lengths of line (many heads use two pieces); use the diameter listed in the manual.
• Feed line into the spool channels and wind evenly and tightly in the direction of the arrow.
• Keep the wraps side-by-side with no overlapping to prevent tangles and feed problems.
• Thread the line ends through the eyelets, reinstall the spool and cap, then pull both ends to set tension.

Winding tips that prevent tangles

Overlapping wraps are the most common reason line jams inside the spool. Use these checks while winding:

What to check	What “good” looks like	What it prevents
Wrap direction	Matches the arrow on the spool	Line won’t bind or unwind wrong
Wrap tension	Firm, even tension	Loose coils that snag
Line routing	In the correct spool grooves	Crossed line and uneven feed
Fill level	Stops below the spool rim	Cap won’t bind, line feeds

If the line will not feed after replacement

• Tap the bump knob on a hard surface while running at near full throttle.
• Make sure the line ends are not melted or fused together.
• Confirm you did not overfill the spool.
• Inspect the head for wear or damage; a worn head can cause constant jamming.

Why it matters

Correct line loading protects the spool and bump-feed mechanism, reduces vibration, and helps your Craftsman 316795861 cut consistently without stopping to clear jams.

To operate your Craftsman gas trimmer model 316795861, start it on a flat, clear area, warm it up briefly, then trim using a smooth side-to-side sweep with the cutting head held slightly above the ground. For model-specific starting and control locations, use the 316795861 owner's manual.

Safe setup before you start

• Wear eye protection, long pants, closed-toe shoes, and hearing protection.
• Clear the area of rocks, wire, and debris that can become projectiles.
• Keep bystanders and pets well away from the trimming zone.
• Check that the throttle trigger moves freely and returns when released.
• Inspect the trimmer head and guard for cracks or missing fasteners.

Basic operating steps (string trimming)

1. Start and warm up: Start the engine and let it idle briefly so it runs smoothly.
2. Set your stance: Hold the front handle with your left hand and the rear handle with your right hand (reverse if left-handed); keep the unit balanced.
3. Trim with the line tip: Use the outer tip of the line, not the whole line length, for cleaner cutting and less bogging.
4. Sweep, do not chop: Sweep in a controlled arc; take light passes in tall grass.
5. Edge vertically: Rotate the trimmer so the cutting path is vertical and walk forward slowly along the edge.

Quick technique guide

Task	Best angle	Best motion	Common mistake
Trimming grass	Head slightly tilted	Side-to-side sweep	Forcing the head into the ground
Edging sidewalks	Head vertical	Slow forward walk	Moving too fast and scalping
Heavy weeds	Head level	Multiple light passes	Full-throttle grinding in one spot

Why it matters

Good technique reduces line breakage, prevents scalping, and helps the engine maintain RPM so your Craftsman trimmer cuts cleanly instead of bogging down.

If it bogs down or won’t stay running

Fuel and airflow issues are the most common causes on gas trimmers.

• Use fresh, properly mixed fuel (if your model is 2-cycle).
• Clean or replace the air filter.
• Check for a clogged muffler/spark arrestor screen.
• If it still surges or stalls, the carburetor may need service or replacement.

For the Craftsman gas trimmer model 316795861, use a 40:1 fuel mix: 40 parts fresh unleaded gasoline to 1 part 2-cycle engine oil. Mix it in an approved fuel can before filling the tank; do not mix fuel in the trimmer’s fuel tank. See the 316795861 operator's manual for the exact fuel and oil recommendations.

Quick mix chart (40:1)

Use this chart to measure oil accurately.

Gasoline amount	2-cycle oil needed (40:1)
1 gallon	3.2 fl oz
2 gallons	6.4 fl oz
1 liter	25 ml
5 liters	125 ml

How we recommend mixing and fueling

• Use fresh unleaded gasoline (stale fuel is a top cause of hard starting).
• Use 2-cycle oil labeled for air-cooled engines.
• Add half the gas to the can, add the oil, then add the remaining gas and shake.
• Fill the trimmer on a cool engine, outdoors, away from ignition sources.
• Store mixed fuel only as long as the oil label recommends; mix smaller batches to avoid waste.

If it runs poorly after mixing fuel

A correct 40:1 mix will not fix a clogged fuel or air system. These checks usually restore performance:

• Replace a dirty air filter (common cause of bogging and stalling).
• Drain old fuel and refill with a fresh 40:1 mix.
• Inspect fuel lines and the fuel tank for cracks or debris.
• If it still will not start or only runs on choke, the carburetor may need service.

Common parts related to fuel and airflow

Symptom	Most common area	Example part for model 316795861
Starts then dies	Fuel delivery	Mtd line trimmer carburetor 753-06288
Won’t rev up, runs rich	Airflow restriction	Mtd line trimmer air filter 753-06417
Fuel smell or leaking	Fuel storage/lines	Engine fuel tank 753-06250

Why it matters

Running too much oil can foul the spark plug and smoke; too little oil can overheat and score the engine. A consistent 40:1 mix protects the engine and keeps the carburetor metering correctly.
