Setup and Installation
1. Pre-Installation Checks

- Inspect the new carburetor for any visible damage or manufacturing defects.
- Gather all necessary tools, which typically include screwdrivers, wrenches, pliers, and a fuel line clamp.
2. Installation Steps
- Prepare the Equipment: Ensure the Stihl TS400 saw is turned off, cool, and the spark plug wire is disconnected. Drain any fuel from the tank.
- Access the Carburetor: Remove the air filter cover, air filter, and any shrouds or covers that obstruct access to the carburetor.
- Disconnect Components: Carefully disconnect the fuel lines, throttle linkage, and choke linkage from the old carburetor. Note their positions for reassembly.
- Remove Old Carburetor: Unbolt the old carburetor from the engine manifold.
- Install New Carburetor: Position the Stens 615-014 carburetor, ensuring any gaskets are properly seated. Secure it with the mounting bolts.

- Reassemble: Replace the air filter, air filter cover, and any other shrouds or covers removed earlier.
Operating Instructions
1. Fuel Requirements
This carburetor is not compatible with fuel containing greater than 10% ethanol. Using fuel with higher ethanol content can cause damage to the carburetor and fuel system components. Always use fresh, clean fuel mixed according to your Stihl TS400 saw's specifications.
2. Initial Start-up
- Fill the fuel tank with the appropriate fuel mixture (less than 10% ethanol).
- Prime the carburetor if your saw has a primer bulb, until fuel is visible.
- Follow your Stihl TS400 saw's specific starting procedure (e.g., choke setting, pull cord).
- Allow the engine to warm up for a few minutes before operating under load.
Maintenance
1. Cleaning
- Regularly inspect the air filter and clean or replace it as needed to prevent dirt from entering the carburetor.
- If the carburetor becomes clogged, it may require disassembly and cleaning with a carburetor cleaner. This should only be performed by individuals with mechanical experience.
2. Adjustments
Carburetor adjustments (idle speed, high/low mixture screws) are typically factory-set. Minor adjustments may be necessary after installation or due to environmental changes. Refer to your Stihl TS400 saw's service manual for specific adjustment procedures. Incorrect adjustments can lead to engine damage or poor performance.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel reaching carburetor, clogged fuel filter, incorrect choke setting, spark plug issue. | Check fuel lines and filter. Ensure fuel tank is full. Verify choke operation. Inspect and clean/replace spark plug. |
| Engine runs poorly/lacks power | Clogged carburetor jets, incorrect fuel mixture, air filter dirty, improper carburetor adjustment. | Clean or replace air filter. Use correct fuel mixture. Adjust carburetor settings (refer to saw manual). Clean carburetor jets. |
| Fuel leaks | Loose fuel lines, damaged gaskets, float needle issue. | Inspect and tighten fuel line connections. Replace damaged gaskets. If float needle is suspected, professional service is recommended. |
