It is extremely important that the engine mount be securely mounted to the airplane’s firewall and that the engine is securely mounted to the engine mount. Follow the instructions included with the airplane for mounting the engine. The engine should be fastened in place with 4 screws through a conventional beam mount. Use 8x32 screws (26GT) or 10x32 (35GT).

At that point reopen the low speed needle by 5–10 minutes.
