How do you check the timing, or change the timing? I almost wonder if the timing isn't retard to far? The service manual only indicates checking for timing advance with the "SmartSpark" system. There is nothing about checking or setting timing.
I know it feels hotter than "normal", but its a completely different engine than I have used before so it might be normal for this breed of engine?
It runs like a scalded dog, even full tilt with fairly heavy grass (61" deck); it hardly changes tune.
Things that can effect the timing on that engine are. A sheared flywheel key, wrong gap from the coil to flywheel, and sparkplug gap. But there is no timing adjustment per say.
