Greetings folks! I have a '07 Recon I picked up this weekend and it has not been used too much except for the guy checking his cattle in his small pasture a few times a week. The idle is a little rough for my liking and will stall if left for 30 seconds to a minute. I have increased the idle but cannot get it to idle smooth. If I pull the choke out slightly it seems to run smoother, which leads me to believe it is running a little lean. I replaced the plug and it was a light tan in color. I also noticed it has small backfire when you rev up the engine and let off the gas as well as when coasting downhill. Again this leads me to believe it is running a little lean. I've read about the air/fuel screw the requires a special D shaped tool. Do I need to adjust this? Also, can you let me know where this adjustment is. Thanks again for all your help guys!!!!!!!!
