Setup and Installation

Proper installation is crucial for the optimal performance of your engine. If you are unsure about any step, consult a qualified technician.

Safety Precautions:

• Ensure the engine is cool and the spark plug wire is disconnected to prevent accidental starting.
• Work in a well-ventilated area.
• Have a fire extinguisher nearby.
• Wear appropriate personal protective equipment, such as gloves and eye protection.

Installation Steps:

1. Drain Fuel: Carefully drain all fuel from the fuel tank into an approved container.
2. Remove Air Filter Assembly: Disconnect and remove the existing air filter housing and air filter.
3. Disconnect Fuel Line: Locate the fuel line connected to the carburetor and disconnect it. Be prepared for residual fuel to leak.
4. Disconnect Linkages: Carefully disconnect any throttle and choke linkages attached to the old carburetor. Note their positions for reassembly.
5. Remove Old Carburetor: Unbolt and remove the old carburetor from the engine. Pay attention to any gaskets or spacers.
6. Install New Gasket: Place the new gasket provided in the kit onto the engine mounting surface.
7. Install New Carburetor: Mount the new Pro Chaser carburetor onto the engine, ensuring it aligns correctly with the gasket and mounting bolts. Secure the bolts, but do not overtighten.
8. Reconnect Linkages: Reattach the throttle and choke linkages to the new carburetor in their original positions.
9. Install New Fuel Filter and Line: Cut the new fuel line to the appropriate length. Install the new fuel filter in the line, ensuring the flow direction is correct (usually indicated by an arrow). Connect the new fuel line to the carburetor and the fuel tank, securing with the provided clamps.
10. Install New Shut Off Valve: If desired, install the new shut off valve in the fuel line between the tank and the fuel filter.
11. Install New Air Filter: Place the new air filter into the air filter housing and reattach the housing to the carburetor.
12. Replace Spark Plug: Remove the old spark plug and install the new spark plug provided in the kit. Ensure it is tightened to the manufacturer's specifications.
13. Refill Fuel: Refill the fuel tank with fresh, appropriate fuel.

Operating Instructions

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

1. Prime the Engine: If your engine has a primer bulb, press it several times until fuel is visible in the fuel line or bulb.
2. Choke Setting: Set the choke lever to the 'CHOKE' position for cold starts. For warm starts, the choke may not be necessary.
3. Throttle Setting: Set the throttle to the 'FAST' or 'START' position.
4. Start Engine: Pull the starter cord firmly or engage the electric starter.
5. Adjust Choke: Once the engine starts and runs smoothly, gradually move the choke lever to the 'RUN' or 'OFF' position.
6. Warm-up: Allow the engine to warm up for a few minutes before engaging any attachments or beginning work.

Maintenance

Regular maintenance of your carburetor kit components ensures longevity and optimal engine performance.

• Air Filter: Inspect the air filter regularly (e.g., every 25 operating hours or annually). Clean or replace it if it appears dirty or clogged. A dirty air filter restricts airflow and can cause the engine to run rich.
• Fuel Filter: Replace the fuel filter annually or if you notice reduced fuel flow or engine performance issues. A clogged fuel filter can starve the carburetor of fuel.
• Spark Plug: Inspect the spark plug annually or every 50 operating hours. Clean or replace it if the electrodes are fouled, worn, or damaged. Ensure the gap is set correctly according to your engine's specifications.
• Fuel System: Use fresh, clean fuel. Consider using a fuel stabilizer if the equipment will be stored for extended periods. Drain the fuel system before long-term storage to prevent gum and varnish buildup in the carburetor.
