Sorry for all of the misunderstanding, and once again thanks so much for all of the help. I found last night that the fuel lines are good, and even tested the line between the high-speed, and the carb..fine. It has to be the low-end, we are currently adjusting the low end needle now, (which we found was screwed well into the carb, which would I guess result in more fuel than air or a rich condition. We have leaned the screw by 2 turns and are now seeing some improvement. I am letting the engine cool now so we can do another test run. It ran on full throttle enough for me to finally tune the high end needle but died from what I guess would be overheating. I pulled the plug to check and see if it was still ok after the dying of the engine, and it was and by the way very clean. I will let you know how the rest goes!
