I have a Kawasaki FC150V on a DR Trimmer/mower. It starts up ok but when power is brought up by engaging the trimmer, the engine soon cuts out and dies. It will also cut out after idling for a minute or so. I've had the carb off and cleaned it thoroughly. It also has decent gravity fuel flow from the tank. Looks like good spark at the plug when removed. Any ideas would sure help, Thanks much, Bob "The sun finally came out in Seattle"
