Well, I thought I had my issues squared away. No such luck. I took it out to clear off some bursh, ran it for about an hour, then it started to cut out. It will run for 30 seconds or more, then cut off then it might fire back up on it's own or it might cut off. When it fires back up, it tends to back fire or rev, so the gas is still getting to it. I feel like it's an electrical problem. Maybe the ceramic ballast resistor or the coil. It behaves just like you are throwing the switch off an on intermittely. Any advice would be appreciated. m-610 bobcat with the wissconsin vh4d 4 cylinder air cooled engine.
