Help!! Tecumseh backfires!!
Hello. I have a Tecumseh snow blower and it runs, but it sounds as if it is backfiring. If I slowly prime it while it is running, however, the problem gets better. I took the carburetor off and rebuilt it (took the welch plugs out, soaked in acid etc.), and it still does the same thing. The flywheel key is perfect, as well as the air gap for the magneto. What is the next step? Perhaps reseating the valves? Thank you for your help.
EDIT: It sounds like it may be a loud misfire possibly?
