I'm the original owner of this nice motor which has served me very well. I thought it had a lot of life left, but I have encountered a problem and I cannot find the solution. The motor runs at full power for about 3 minutes and then suddenly loses most of its power and just moves along at about 1/3 power. I have replaced the plugs, the plug wires, the fuel pump, and the coil (twice). I have completely cleaned the carburetor (twice) and done the carb kit. I replaced the fuel lines all the way to the tank. At one point I noticed that a coil was cracked and I thought for sure that was the problem. But even with the new coil I get the same problem. I'm at the end of my rope here and just about ready to give up. If anyone has any idea, I would appreciate it. I love this little motor -- it has been very reliable. Always starts very easily and runs smoothly, until this loss of power started happening. Thank you for any advice you can offer. John
