Bought a new Cub Cadet wheeled trimmer, the manual that came with it for the engine is an MTD engine manual. Ut is a 195cc OHV motor. For spark plug replacement info they only givre you the MTD part number. Their is a charcol canister filter that you may or maynot have to replace depending on how dirty it gets, but no part number given. Also no information on what the lash setting is for he valves. Called MTD they were no help sbasically sid most people din't wnat to be bothered to set valve lash so he didn't have any specs. So if any one can supply the missing info I would greatly appreciate it.
