On a B&S 195 OHV am having to replace head gasket again after two weeks on first replacement. Not started work yet but quick look at, and it seems to be blown in same place on side. The first gasket came off real clean, did not stick anywhere and was all in one piece except where blpwn. Surfaces were shiny clean on engine and gasket was replaced, though not specifically torqued. Did not observe this happening but was told the engine backfired and then would not restart. Anyone have ideas about what may be happening and what I should be looking for on this second replacement?
