HPI Racing Fuelie 26S 15403 Instruction Manual

The recommended fuel mixture for the HPI Racing Fuelie 26S 15403 Engine is a 25:1 ratio of gasoline to two-stroke oil.
If the engine won't start, check the spark plug for fouling, ensure the fuel mixture is correct, and verify that the carburetor settings are as per the manufacturer's specifications.
After each use, clean the air filter, check for any loose screws or bolts, inspect the spark plug, and ensure the engine is free of dirt and debris.
To adjust the carburetor, start with the factory settings, then fine-tune the high-speed and low-speed needles until the engine runs smoothly at all RPMs.
The recommended spark plug for the Fuelie 26S engine is an NGK CMR7H or equivalent.
Ensure proper airflow to the engine, avoid running at full throttle for extended periods, and maintain the correct fuel mixture ratio.
The engine may stall at idle due to incorrect carburetor settings, clogged air filter, or a fouled spark plug. Adjust the idle screw and clean the air filter and spark plug.
Excessive smoke may indicate an overly rich fuel mixture. Verify the fuel ratio and adjust the carburetor's high-speed needle to lean out the mixture if necessary.
The air filter should be inspected and cleaned after each use and replaced if it shows signs of wear or damage.
For breaking in a new engine, run it at a rich fuel mixture for the first few tanks, avoiding full throttle, and allow it to cool down between runs.
