A week or so ago, I was mowing with my 1995 Craftsman lawn tractor with 15 HP B&S engine (Model 28N707). I heard what I thought sounded like a rod knocking, so I shut it down, checked the oil and I was down a quart (holds 1.5 qt). Hmmm, I thought, my Briggs is toast. So I started pricing replacements, $600 was about the best I could do, and I'm not willing to part with that kind of cash without a fight, so I decide to at least open the engine up. Well, I think I see the problem. There are 10 bolts holding the crankcase together, one was missing, one had no threads engaged, two were turned out at least two threads, and two were just finger tight. The danged thing was held together with only 4 of the 10 bolts! It has run very well for 5 years. I have always been leary of B&S in the past, but this experience tells me that the design is sound, but they have (well, had) some pretty darn poor assembly workers. I will be tearing it down and checking the internals (and all bolts) this weekend, but it's starting to look like I might get out of this for the price of a gasket set.
