In regards to a 15HP Kawasaki. Ok, so on Thursday I am mowing a lawn and the next thing I know oil is shooting out of my oil filler tube. ( I think that it got loose from mowing beside some pine trees) I quickly stop the mower and tighten down the oil filler cap, check the oil level, and then continue to mow. Well, I noticed that it was kind of bogging down and it seemed like it didn't have that much horsepower. It was coming and going. I also noticed that I was burning oil. I finished up my work and went home. I charged the spark plugs in it, put some dry gas in the tank on Friday and fired it up, seemed ok, but not all there in regards to horsepower and it was stuttering. I figure I didn't want to mess with it anymore because I was sick. So today after running it we pull the plugs and they are blacker than heck. We check the plugs to make sure they are firing, clean the new plugs, check the coils, drain the oil in the mower, and put some new in and also adjusted the carbator. Thought that would solve the problem. We start it back up and we noticed though that one of the cylinders didn't seem like it was firing that great. So we take off the rocker case cover and notice that one of the rods (don't know the exact name of it) was out of place and not connected properly also noticed a metal shaving there, but thought that it could just be wear from running. We connect it up to the rocker put everything back together and fire it up. Still the horsepower is lacking. Even when I engaged the mowerdeck the engine almost stalls. So we shut it down, open up the rocker case again and now both of the rods in there are not hooked up. In fact now one of them is bent. So tell me fellows. What is wrong here and how can I fix it? Better to just get a new engine.
