Setup and Installation

Before beginning installation, ensure your trimmer is turned off and cooled down. Disconnect the spark plug wire to prevent accidental starting. It is recommended to wear appropriate safety gear, such as gloves and eye protection.

Step-by-Step Installation:

1. Prepare the Trimmer: Drain any remaining fuel from the fuel tank. Place the trimmer on a stable, flat surface.
2. Remove Air Filter Cover: Locate and remove the air filter cover and air filter element. This will expose the carburetor.
3. Disconnect Fuel Lines: Carefully disconnect the fuel lines from the existing carburetor. Note which line goes to the primer bulb and which goes to the fuel tank.
4. Remove Throttle Linkage: Disconnect the throttle linkage from the carburetor.
5. Unmount Old Carburetor: Remove the mounting bolts or nuts that secure the carburetor to the engine. Carefully pull the old carburetor away from the engine.
6. Replace Gaskets: Remove and discard the old carburetor gaskets. Install the new gaskets provided in the kit. Ensure they are correctly oriented.
7. Install New Carburetor: Mount the new Fricgore carburetor onto the engine, aligning it with the mounting studs. Secure it with the original bolts/nuts.
8. Reconnect Throttle Linkage: Reattach the throttle linkage to the new carburetor. Ensure it moves freely.
9. Connect Fuel Lines: Reconnect the fuel lines to the new carburetor. If replacing fuel lines or fuel filters, do so now. The kit includes new fuel lines and filters for this purpose.
10. Replace Primer Bulb (if necessary): If your old primer bulb is cracked or hardened, replace it with one of the new primer bulbs from the kit.
11. Replace Spark Plug: Using a spark plug wrench, remove the old spark plug. Install the new spark plug provided in the kit. Do not overtighten.
12. Reassemble: Reinstall the air filter element and air filter cover.

Operating Instructions (After Carburetor Replacement)

After installing the new carburetor, follow these steps to start and operate your trimmer:

1. Refuel: Fill the fuel tank with the appropriate fuel mixture (gasoline and 2-stroke oil, as specified by your trimmer's manufacturer).
2. Prime the Carburetor: Press the primer bulb repeatedly (usually 7-10 times) until fuel is visible in the bulb and flows freely through the fuel lines.
3. Choke Setting: Set the choke lever to the "Full Choke" position (cold start).
4. Starting: Pull the starter rope firmly and steadily until the engine "pops" or attempts to start.
5. Partial Choke/Run: Once the engine pops, move the choke lever to the "Half Choke" or "Run" position (depending on your trimmer model).
6. Restart: Pull the starter rope again until the engine starts and runs smoothly.
7. Warm-up: Allow the engine to warm up for a minute or two before engaging the throttle fully.

Carburetor Adjustment:

Your new carburetor is typically pre-set for optimal performance. However, minor adjustments may be necessary for specific environmental conditions or if the engine is not running smoothly. Use the provided adjustment tool for this purpose.

• Idle Speed (T screw): Adjusts the engine's idle speed. Turn clockwise to increase, counter-clockwise to decrease.
• Low Speed (L screw): Controls the fuel mixture at low RPMs. Affects acceleration and idle quality.
• High Speed (H screw): Controls the fuel mixture at high RPMs. Affects maximum power and engine temperature.

Caution: Carburetor adjustments should be done carefully. Incorrect adjustments can lead to engine damage. If unsure, consult a qualified technician.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your carburetor and trimmer.

• Fuel Filters: Replace fuel filters periodically (e.g., annually or every 50 hours of operation) to prevent contaminants from reaching the carburetor. The kit includes two fuel filters for future replacements.
• Air Filter: Clean or replace the air filter regularly. A dirty air filter can restrict airflow and affect carburetor performance.
• Spark Plug: Inspect the spark plug for wear or fouling. Replace if necessary. The included spark plug is a new replacement.
• Fuel Quality: Always use fresh, clean fuel mixed with the correct ratio of 2-stroke oil. Stale fuel or incorrect mixtures can cause carburetor issues.
• Storage: Before long-term storage, drain the fuel tank and run the engine until it runs out of fuel to clear the carburetor. Alternatively, use a fuel stabilizer.
