Well I had someone give me this Stihl BR400 blower that quit working on them. I'm not sure what that means.. If it died, or just wouldn't start one day. Anyhow, it a decent looking blower. I just can't get the bastard to run. Here is what I know and what I've done. Conditions: Compression around 120psi Unit gets spark while using my spark tester My Spark tester Tries to run after a little starting fluid (with upper cylinder lubricant) What I've done: Checked Flywheel and key - Magnets were strong, key not sheared Regapped coil New NGK Plug Soaked Carb in Seafoam and replaced diaphragms and pump Checked Carb mounting flange/spacer for cracks and replaced gaskets New Fuel Line Checked Fuel Filter Removed spark arrestor screen Removed muffler and torched the inside What really puzzles me as I try to troubleshoot this blower is, Spark always test good (according to my method) and the plug always seems wet and smells like fuel after cranking. My first inclination when I got this blower was the coil, and I still don't trust it. But if the coil was bad would the engine run for a few seconds on starting fluid? What am I missing here? Should I replace the Carb? Coil? What does everybody think? I really appreciate everyones help. I can link you to a Parts Guide and Service Manual if needed.
