Small Engine Lookup

I built Small Engine Lookup, a free source-linked engine reference site. The Honda GX390 lookup matches seven supported serial ranges to four Honda manuals for oil capacity, oil grade and spark plug details. Engine oil and the supported reduction-case oil are kept separate. The site also lists nine repair providers around Knoxville and Spokane. Built with Astro and TypeScript, hosted on Cloudflare, with AI assistance and checks against manufacturer sources. No signup is required. It is a limited reference tool, not a universal engine decoder or repair diagnosis.
