Craftsman 917773753 high wheel line trimmer Parts

When your Craftsman high wheel line trimmer model 917773753 dies as you squeeze the throttle, the most common cause is a fuel and air mixture problem, usually from a dirty air filter, stale fuel, or a restricted carburetor circuit. Start with the quick maintenance checks in the 917773753 owner's manual.

• Replace or clean the air filter (a dirty filter can make the engine run overly rich and stall).
• Drain old fuel and refill with fresh gasoline (stale fuel causes hesitation and stalling).
• Check the spark plug condition and gap; this model uses a Champion RJ19LM or J19LM with a 0.030 in gap.
• Make sure the throttle control lever is in the correct position (if equipped).
• Inspect for grass and debris buildup under the trimmer that can load the engine.

Your carburetor uses a nonadjustable fixed main jet, so “turning screws” is not the right fix. If the engine still stalls after fresh fuel and basic tune-up items, the carburetor likely needs cleaning or service by a qualified technician.

1. Replace the air filter.
2. Replace the spark plug (or clean and regap to 0.030 in).
3. Refresh fuel and confirm the fuel can is clean (rust or dirt in the can causes repeat problems).
4. Clean debris from under the trimmer and around the cutting head area.

Stalling on acceleration is usually the first sign the engine is not getting the right air-fuel mix or is being overloaded. Fixing it early prevents hard starting, loss of power, and premature wear on drive components.

For Craftsman high wheel line trimmer model 917773753, use a 40:1 gasoline-to-2-cycle oil mix (40 parts fresh unleaded gasoline to 1 part 2-cycle engine oil). This model uses mixed fuel, not straight gas; follow the mixing and fueling steps in the 917773753 owner's manual.

• Use fresh unleaded regular gasoline (do not use old or stale fuel)
• Use 2-cycle engine oil labeled for air-cooled engines
• Mix fuel in an approved gas can, not in the trimmer tank
• Shake the container well before fueling, and re-shake if it sits
• Only mix what you will use soon to keep starting and performance consistent

• Do not start the engine
• Drain the tank completely and refill with the correct 40:1 mix
• If the engine was run, replace the spark plug and inspect the fuel system before continued use

A 2-cycle engine depends on oil mixed into the gasoline for lubrication. Running straight gasoline causes rapid internal wear and can seize the engine; the correct 40:1 mix protects the piston and crank bearings and keeps the trimmer running reliably.

On the Craftsman 917773753 high wheel line trimmer, you replace the cutting line by removing the worn line from the carrier plate, cutting new line to the specified length, then locking it under the retainer clips so both cutting ends match. Follow the steps in the 917773753 manual.

• Disconnect the spark plug wire and keep it away from the spark plug.
• Let the engine and muffler cool completely.
• Stabilize the trimmer on a flat surface so it cannot roll.
• Wear gloves and eye protection; line ends can snap back.

Use the same process for both sides of the head:

• Remove the worn trimmer line from the line carrier plate.
• Cut a new piece of trimmer line to the length specified for this model.
• Fold the new 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 seats fully under the retainer clip.
• Repeat on the other side; confirm both cutting ends are the same length.

Replace the trimmer line when it is worn to less than half its original length. Running short line reduces cutting performance and increases vibration.

Correctly installed, equal-length line cuts cleaner, reduces shake, and helps prevent premature wear on the trimmer head components.
