Mowing the lawn should be a thing of relaxation. But when you have a mower like mine, you will NEVER be able to relax on the trip home knowing that the first thing you must do is get the mower running before actually using it. I have a Briggs 16.5 hp OHV engine that will not turn over. New battery, new solenoid, new starter. I am under the assumption that one of my safety cut-off switches is bad. How do check them? Also, I can jump the starter off with jumper cables, and it turns over, but it does not fire...fouled plug? And when it does not start, it shoots fuel out the exhaust...is this a major problem, or is it due to the plug not firing?? Please help, thanks Jimmy B.!!

Hi. I've installed new piston rings in my old Briggs&Stratton lawnmower (model # 95902). 3 HP engine or something like that. 65.09 mm piston. At first, after testing it at home for about ten minutes, on easy low grass, it did not smoke at all, but yesterday I went to my aunt's house and tried it there on much thicker and higher grass and after I checked oil today, it's more than half gone (oil dish takes about 0.5 liter of it, so it must have burned around 0.3 liter in about hour of work). I've noticed blue smoke but only when the grass was higher, when the engine was at maximum stress, I haven't noticed it when it was cutting smaller or less thick grass. When I was installing rings, I watched to orientate them properly (gaps in 120 degrees from each other), but I'm not sure if it have moved when I pressed it with this tool to fit rings to cylinder bore(don't know it's right name, I'm from Croatia): [url]http://vedris.com/hrvatska/images/uploads/selna-izjednacavanje-potenc.jpg[/url] Now, I'd like to know could this misorientation (if existed), cause this much oil to burn? Or could it be just because the rings are new and aren't "nested" quite well yet, maybe it'll stop burning oil after few more working hours with new rings? Or is there a bigger problem and it won't go away? I've checked the cylinder bore for deeper scratches and there were some scratches, but not that deep. I took the engine to a guy who has more grasp in engines then I do and he said that new rings should do the trick to stop it from burning more oil. Here are few pics of the engine before I installed new rings: [url=http://www.mediafire.com/?w0m22czzwgi]pics.rar[/url]
