12 hp Briggs and stratton won't start
I have a craftsman lawn tractor that was given to me when I got it it wouldn't run so I ran some tests and found that the carb was very green and dirty so I replaced the float bowl, needle , gaskets , nozzle etc. Also replaced filters and fuel line after words it fired right up ran great I parked it in the garage and the next mourning it wouldn't start.. I went out and bought a brand new battery today installed it and it fired right up again! Left it maybe 2 hours and now it don't start I mean nothing seems like the battery's dead. Any ideas tips please help
