- My usually reliable lawn tractor has decided not to run in the 0-5 degree outside temps (plowing snow). It starts, runs for less than a minute ..up to a couple of minutes then dies. Even died after running long enough to thoroughly warm up. Plugs were replaced, and it's getting spark, and air. For the short time it runs, it appears to run fine I've liberally doused the carburetor with carb cleaner. I'm suspicious of the in-line fuel filter ..the size of a quarter, with inlet on one side, and outlet on the other. Tractor is 12 years old. Filter never changed. Outside temp has usually not been a problem so maybe just a coincidence. Any thoughts?
- Also, what delivers fuel from the gas tank on an older Sears lawn tractor the engine? Is there a pump, or is it just gravity or some kind of vacuum feed?
Thanks
