It was compatible with my model with no issues. Before installing the kit, it would take several pulls to start and now it starts up on the first pull. It was also very easy to install and I only needed a few tools pictured. The spark plug was also gapped properly and ready to install. The kit includes an air filter, spark plug and gas filter. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/115603487-fs56rc-tune-up-kit-air-filter-for-sthil-fs40c-km56rc](https://www.desertcart.us/products/115603487-fs56rc-tune-up-kit-air-filter-for-sthil-fs40c-km56rc) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-18*
