My X360 just started acting up on me. It starts and runs fine for about 5 minutes and then it starts to sputter, backfire and stall. I've checked the inline fuel filter and it's clean, air filter is clean. Gas is fresh. I haven't gotten into the carb yet. I thought I'd look for some advice before I possibly go in the wrong direction. The tractor has 200 hours on it. I bought it used a few years ago with about 160 hours on it. I've changed the oil and serviced the deck etc. since I've owned it but I haven't done anything with the carb or plugs.
Any advice would be great.
