Trouble With Exmark Kohler CH740 Engine
The engine runs fine all the way up to about half throttle, after that it starts missing out/bogging down, just no power. I've replaced the coils, the spark plugs, the entire carb, the fuel filter, a valve that didn't seem to be seating properly (most likely was fine) I've pulled the flywheel to make sure the keyway wasn't sheared.
It is getting plenty of fuel, seems to be a timing issue almost, at a total loss!!! Any Suggestions???
