Why would my ATV be using a lot more gas then it used to? I have a 2001 Magnum 325 4X4 and it was guzzling gas, running very rich. I have the carb apart and think the diaphragm may be damaged because it appears to be stretched out of shape. Also, do the needles where out? This carb has never been adjusted or worked on before. The motor was running and starting okay, but using way too much gas. Any advice?
