I had two previous Craft. mowers, both 12hp 38". No complaints used them hard, have a half acre to mow plus hauling wagons of firewood up hills.. Each one lasted 10 yrs. Didn't do anything but change the oil. and batteries. (clutches went out)........ Now my new one I bought in 2013, 42" 420cc, 2yr. extended war. ($200.) So I had 3 yrs. war. So under war. Sears had to replace the starter and the flywheel which had teeth chewed off and the battery. .... So now the ext. war. is up and I got carb. problems.... Sears service call is $99. plus $60/hr. labor+ parts. So i'm thinking i'll just slap on a whole new carb, I can handle that..S o I goes online, to check the price>>>>>>Carb assembly is no longer available. Tractor is four yrs. old and they prob. sold 1000s of these. What???
