Craftsman mower with 19 horse Briggs engine will not start/crank

My craftsman 19 hp lawn tractor with a Briggs and Stratton engine that is 3 years old and just out of warranty won't start. It will start to crank but won't go all the way around, then backfires through the carb. I have checked the battery, for too much oil, flooding, had the flywheel off to inspect it and the key/keyway, adjusted the valves, probably left out other things. I did get it to start once since this happened by having my wife hold the key while I forced it through the cycle turning the flywheel by hand and it ran good with no noticeable problems but I have not since been able to get it to start like that again. It will just go through that stroke then backfire and/or stop before it can go through another stroke. If I adjust the valves too loose it might go through 2-3 strokes but will backfire each time and not start. I am lost for a reason this has happened. I used it one day for a few hours and went to move it the next and it has been like this ever since. Thanks, Bill

Sounds like the automatic compression release on the cam has gone bad.

2008 Craftsman lawn tractor


Tip for 2008 Craftsman lawn tractor that runs for about 30 minutes then starts to cut out and dies, and will not restart. These tractors have a defective gas cap that will not vent. Simply remove gas cap and reinstall loosely. The best fix is replace gas cap. If your tractor is less than two years old Sears will replace it free. preview_graphic.jpg

24 hp Briggs Stratton sears riding mower engine wont start unless you use start fluid cleaned filter have flow to engine


If the mower starts and continues to run after injecting, you may want to make sure the choke is working properly. If the choke plate is not closing all the way, it will make cold starts difficult.

10 A Fuse blows each time I shut off engine. Short somewhere? Suggestions? Craftsman 19 hp Briggs & Stratton 42 inch deck. Probably 10 years old. Thanks! Mike


Yes, probably a short, and I think you should look at the ignition switch as the first suspect. It has two switches inside - one to send battery power to the various components, and a separate one to ground out the magneto when the mower is turned off. Could be a short between the two parts of the switch. Test it if you have the tools, otherwise try replacing it. Good luck! If this is helpful, please take a moment to rate my solutions, thanks!

Craftsman 19.5 HP Briggs and Stratton engine. Will not start. will start with starter fluid and then stalls. It appears no gas is getting to the carb.


disconnect fuel line from carb and crank engine. NO FUEL-check in-line fuel filter, kinked line, trash or water in bottom of fuel tank. FUEL- gas is stale, has water in it, or carb has sediment in bowl, bottom jet or idle jet.or float could be stuck shut.

flop the seat forward, push the connector firmly onto the seat switch [in the middle of the seat underside], should solve your problem, or the switch could be bad, but not likely unless you're 300lbs
