I have a Shindaiwa T261x that idles but when I try to throttle it dies. The strange thing is that I have replaced the carburetor with a new one, replaced the fuel filter and the spark plug and the problem persists. (?? ) The only thing I can think of remaining is the coil/magneto, but don't those almost never go out?

Hi,
Suggest that you check the muffler screen and exhaust port for carbon buildup
Peace,
