when it rains it pours...
Okay, blue splitter is having a problem. This machine has split a LOT of wood, it probably don't owe me anything. Figure it did the lions share of 300 cords a year for atleast 6 years... Kohler Command CH15. One heck of a engine, my hat comes off to think of the hours and hours of turning a 22gpm pump at 3600rpm. Kurt fired it up today and it sounded like a REALLY loud rap like a really loose lifter on a chevy. It is that sharp a sound. Engine still runs but sounds terrible. This engine has oil pump and filter, and I have a gauge on there. Pressure is normal. Follow the hunch, and pull the valve cover. nothing looks funny here. start it up, and the valves are opening/closing. pulling it over by hand, and I notice a oddity with the action of the exhaust valve. Intake opens piston goes down... then the exhaust opens just a bit... then compression and then the exhaust valve opens like it should. then intake again and the extra opening of the exhaust valve again. WTF ? Is this Kohlers idea of EGR ?? or something even weirder?
Like I said, this engine has pretty much 2000 hours on it, starting to blow by a little. I am wondering what my best course of action is here. Take it apart and try and fix it. or just hang another engine on it?
Another Kohler? Try for a Chonda? I don't know if it really needed 15hp, but the 22gpm pump calls for 12hp, and I am at elevation up here. 15 seemed sensible. I don't ever recall it struggling tho.... Might get by with a 13 or so?
Thots and feedback appreciated
