Assembly & Operating FAQ

Do these engines actually run?

Yes! Every internal combustion engine runs on real 92# gasoline or nitro/methanol glow fuel. Our Stirling models run on heat from an alcohol lamp or boiling water.

Are replacement parts available?

Yes. We stock complete spare parts—from gaskets and spark plugs to pistons, camshafts, and gears—in our Replacement Parts Center.

Do you provide assembly manuals?

Every kit arrives with an illustrated step-by-step schematic manual detailing each sub-assembly.
