i have an older toro 52" walk behind. i was told that it was a kawasaki 12 hp engine but the stickers and numbers are missing! i was wondering if anyone on he has a similar mower or is familiar with this mower. it is 12-14 years old but in good condition. when started the idle is rough and the blades don't engage. i took the carb off and it seems that someone has messed with the jet. i was wondering if and one has the same motor and can tell me the numbers so i can get a new jet and not get raped by the service shop! thanks jamie @ lucky lawn landscaping
