After removing the muffler the problem seemed to abate - but not entirely. At last I replaced the burner tube and now it's working OK. But I'm going to leave the muffler off in the hope that a leaner air/fuel mixture will help reduce carbon buildup in the burner tube and chamber.
Did you notice an appreciable difference in the noise level without the muffler verses with the muffler ?
