Hi, New to the forum and JD garden tractors. I acquired one from my father... but having some trouble. It won't start in cold weather. I turns over fine, but eventually backfires through the muffler like a shotgun. It ran fine in the summer, but once the cooler weather hit it won't start. I'm learning he had the same problem last year with it (but it was never fixed). I hit it with ether...that didn't work. Checked the spark, spark and gap look good. I'd assume it's a fuel issue, but if that were the case, why wouldn't ether at least fire it up? Any ideas why the temp is a factor and where to start? Thanks!
