First of all make sure the muffler is on really tight. Next try fattening up the mixture a couple of clicks; if no joy there try leaning a couple of clicks. Finally if still no joy, check out the fuel line pluming especially inside the tank. My last suggestion would be to try a new glow plug.The older I get, the fewer things seem worth waiting in line for.
