I have 2 briggs and stratton, one starts easy, one doesnt, three victas 2 start hard and one easy, and one 4hp tecumseh that is the easyest of all to start. none of them stop until you want them to, an all seem to have good compression, far as i can tell, dont know anything about decompression features. I have even swaped all the carbys around and they all do the same? cheers.
