when i look at the bottom of the car, i see 2 gears. one is smaller and longer and one is bigger. both have teeth. which one is the flywheel?
The one that is actually attached to the engine. It's also metal and would only have very very short teeth. In fact, it's more ridges than actual teeth.
The spur gear is plastic, should have longer teeth, and it's attached to the center differential instead of the engine.
I HIGHLY suggest getting very familiar with the parts explosion sheet in your manual.
