I have a Craftsman Eager1 24" two stage with a Tecumseh motor and pull start. The model # is: 536 90560 and until tonight I had never heard it run. I had no spark, so I pulled the flywheel and cleaned the magneto contacts. After re-assembly it started well, so I took it outside. I got about 40', and the engine died. I re-started it with one pull and got about the same distance before it died again this time with no spark again. I replaced the plug in hoping it was just that simple, but still nothing. I've never had a small engine run so well, then just die like that with no spark. Any ideas you have are appreciated.
