Roll the flywheel until the right-hand edge of the metal magnet cover just bumps a straight edge held against the right-hand edge of the right-hand coil leg.
Here it is from a slightly different angle without the straight edge.
Now just read the degree wheel.
This flywheel is in tolerance because it is set at 15° BTDC (counter clock-wise rotation) which is less than the 18° BTDC maximum allowed in the Box Stock rules.
Click HERE to download a paper degree wheel the perfect diameter for a GX200 engine. Paste it to cardboard and cut it out, then drill the center just big enough for your clutch bolt.
SPECIAL NOTE: For those using an ARC Billet Flywheel (such as Road Racers) "Stock" timing is 24° BTDC maximum with the flywheel positioned as pictured below.
