I bought a new Kohler CV14 motor, and I got it mounted in my SGAG 36" Hydro walk behind without any problems. Once I got it started, it idles really low, and it doesn't seam to rev high. If I put my throttle all the way on fast, as soon as I put either the blades on or the trans out of neutral the thing wants to die. I played around with the air screw, and different places to mount the throttle cable. I'm just not sure what is wrong. Maybe I have the throttle cable mounted in the wrong place. It certainly doesn't help that I don't have the manual.
