I have a 2011 mule KAF400EBF. Bought it new. Ran good all these years until last February when it started blowing white smoke and lost power. Looked on the web and found out it was the carb causing it. Took it to a repair shop and they looked at it and put a new OEM carb on it for $350 including a tune up. The shop owner said that aftermarket carbs are not reliable and I should part with the $170 to get an OEM carb. Now it is December and it is blowing smoke again and has no power. Forget trying to get any warranty from the repair shop. Since it is not rocket science, I ordered a new aftermarket for $45 and am waiting for it to come in., I figure if the OEM only lasts nine months. why spend the extra money. Meantime, I pulled the carb, cleaned it and blew out the orfices with air to no effect. Has anyone experienced this problem and found out what is wrong with the carb? No oil or fuel in the airbox but am getting excessive fuel out the exhaust (can see it on the ground). For those who are not familiar, the mule is air cooled so comments about water are no help. New to the forum and appreciate any information.

As an update to the above, I have found out some things. The smoking comes from overfilling the oil reservoir. From what I have found out, three things can cause this. One is accidentally overfilling the oil level with oil. Two, a sticking carb float. (I understand there is no overflow on the carb) causing the crankcase to overfill with an oil/gas mixture. Three, a bad fuel pump allowing fuel to flow to the crankcase through the vacuum line, again overfilling the crankcase. My problem last February was the carburetor. This time it was the fuel pump. In each case the oil level was very high, and the oil was diluted with gasoline. At After replacing the fuel pump, I drained the oil/gas mixture from the crankcase and put on a new filter. The vehicle ran well, but it still smoked some, so I replaced the oil and filter a second time, after which, the smoking stopped. I read that one individual replaced the fuel pump with an electric fuel pump, eliminating the vacuum line to the crankcase. I am considering doing this. He used a Mr. Gasket 42s electric fuel pump available on Amazon for around $40.
