Murray B&S riding mower turns over but never fires
Hello, I have an older model Murray riding mower with a briggs and stratton 13.5 HP OVH motor, Nikki carb. I just acquired this recently and after charging up the battery, it started up once and shut off almost immediately. Since then I have been unable to get it fired up again. I've changed the spark plug, and checked the carb (to what extent I know how), the floater moves freely and the anti whatever solenoid closes and opens when the key is in the 'on' position, with good voltage going to the wires. I have good spark as well. The engine turns very strong, but never fires up, just turns over and over. I don't have alot of experience in the small engine world, and I couldn't find a short anywhere, other than the headlights don't come on and I dont see any power from the wire coming out of the key switch. Any ideas? Thanks for anything that can be done to help!

Sounds like you have done a good job of trouble shooting. You should check again and see if there is spark at the spark plug. If so great. If not you need to bypass the key switch and try again. Are you getting fuel, a dirty carb can look clean, the smallest spec of dirt can get in a jet and drive you crazy trying to find it. If you are getting fuel is it fresh? Old gas is one of the biggest causes of a no start situation,change your fuel. If these things pass you will need to check compression or even pull the muffler off and look for scoring on the piston and cylinder.if this is the case you ne to rebuild the engine.these are basic quick things to check and one of them will tell you what the problem is. good luck.
