I have 2000 yard machine 13hp .. I know what I did wrong... I added too much oil and had white smoking coming out the front exhaust/carb ... So i changed my oil and it kept doing the same thing.. Alot of white smoke.. I tried cleaning couple thing but i have no idea what im doing.. After 2 days of trying to start it it wont start at all anymore.. There is crank but its weak.. Any help would be great
