Warranty Information

  • Q: What is the warranty on an LCT engine?

    A warranty statement is incorporated in the engine Operator’s Manual. Essentially, the LCT warranty covers defects in material and/or workmanship. A purchase receipt is required for all warranty claims.  Most engines are covered by a Two Year warranty, except when used commercially or on rental equipment where the coverage is for One Year.

Operation, Troubleshooting and Storage

  • Q: How do I find out what model engine I have?

    The engine model number is engraved into the engine block on the flat side opposite the spark plug. The model number will start with a ‘LMH’, ‘PLMH’, ‘PLX” or ‘PW’. The model number is the first two of three lines of information in this area. This information is essential when requiring service or requesting parts information. Visit our Service Page to see a diagram of where your engine model number is located.

  • Q: What type of oil goes in my engine and how much?

    Engine oil recommendations are located in the engine Operator’s Manual. LCT recommends using a high quality 4-stroke automotive detergent oil. The oil should be checked before each engine use and changed after the initial break-in period of 20 hours.  Regular oil changes should occur every 40 hours or 6 months of operation, whichever comes first. Engines without a high oil fill tube dip stick, refer to the drawing for checking oil.

  • Q: How should I store my engine?

    Short-term storage (up to 3 months):

    • Remove debris from the engine to facilitate adequate cooling and reduce the risk of excessive heat buildup.
    • To avoid stale gas and carburetor problems, treat fuel with fuel stabilizer. Add according to manufacturer’s instructions.
    • After adding stabilizer, run engine for 10 minutes outdoors and away from sources of ignition to allow fuel to reach the carburetor.


    Long-term storage (over 3 months):

    • Remove debris from the engine to facilitate adequate cooling and reduce the risk of excessive heat buildup.
    • Empty fuel tank by running engine outdoors until it stops. *WARNING* NEVER leave engine unattended when it is running, and NEVER run engine in  enclosed areas.
    • Lubricate cylinder bore to avoid corrosion.

    If you have any questions regarding any of these processes, please consult your engine Operator’s Manual.
