I'm thinking about replacing the honda gx200 engine on my 2007? permagreen magnum. I only do 20 some yards but can't have it broke down when i need it. It has 1030hrs on it, as far as I know its the original motor. Runs good, but occasionally leaks oil out the bottom somewhere. I pulled the engine and took the shield off the bottom of the head and it was full of dirt and crud. Does anyone have a good used engine for sale? And does anyone know if the Kohler courage 6.5hp is direct replacement?? Not sure whose local honda dealer, but my friend used to work at kohler dealer and that engine is supposed to be direct replacement, and only cost 250 or so.
