According to LCT, all new engines come with a manufacturer's warranty against defects in materials or workmanship. LCT states to hang on to your receipt. In case of problems return to the distributor for repair or replacement. Of course, if you run the engine out of oil or neglect to clean the air filter, the warranty will not cover owner neglect.
The engine has an oil sensor cut-off switch. When the oil level is too low, the sensor shuts of the engine. This is a safety feature built into the engine. If this engine is used on a go-kart, the g-forces of turning and going over bumps sloshes the oil in the crankcase. Go-kart owners report the sensor "thinks" the engine is low on oil, and shuts off the engine. Owners report they disconnect the oil sensor, so their engine keeps running. This procedure is risky, since if the engine does indeed run low on oil, it will self-destruct. If you do this, always check the oil level frequently, since the manufacturer's warranty will not cover owner-induced damage.
Engine owners are given a troubleshooting guide by LCT engines. Some of the areas addressed are hard starting, poor idling, or lack of power. LCT offers some possible solutions for every problem. A worn spark plug is a very common problem with small engines. If you are having problems, inspect the spark plug first.
