The flywheel is connected directly to the engine, on the opposite side to the pullstart. They are circular and usually made of aluminium or steel. If you turn the car upside down you should be able to see it's edge through one of the machined slots in the chassis.

The clutch is connected to the flywheel. The clutch BELL has the smaller "cog" or PINION gear on it. This is the smaller gear of the two - the larger gear is the SPUR gear. These cars do not have slipper clutches.

I hope that made sense and you now know where some things are and what they are called!
