flywheel/coil

I have the ARC with the ring gear and I can't find the little piece of paper with the proper gapping number? Little help:shrug:

Low Hrs Briggs flywheel and coil from a 3.5hp. I thought this is what guys put on the 5hp and such as a poor mans flywheel upgrade. That's why i removed it when junking the motor. Make offer+shipping. $15-20?
