If your engine requires additional parts beyond the standard rebuild kit (e.g., crankshafts, coils, starters, plug connectors, or cables), we will contact you before any work is done. These items will be billed at MSRP with full transparency.

SHIPPING & PACKING INSTRUCTIONS

To protect your engine in transit:

Do not send radiator, harness, water pump, or hoses
Pack the engine separately from the carburetor, inside a heavy-duty box (Home Depot boxes recommended)
Cushion the bottom, sides, and top heavily with bubble wrap
Ensure the engine is immobile inside the box — no movement side to side, up or down
Once packed, shake the box gently — if it moves, repack

We cannot accept damaged shipments due to poor packaging. Protect your investment.

NOT INCLUDED – READ CAREFULLY

This rebuild does not include:

Radiator
Wiring Harness
Water Pump
Hoses

Please do not send these parts. These components are essential to your engine’s cooling and reliability. It's your responsibility to ensure they are in excellent condition, as poor cooling or electrical systems can compromise the life of your freshly rebuilt engine.
