I have two flywheels that I removed from 2 different A-series engines. One from an A12 & one from an A14. The A12 looks lightened substantially, its diameter is 9 7/8" , theres approximately a 3/4" deep recess from the ring gear surface to the clutch surface. The A14 one is 10 3/4" diameter & flush across the surface. It looks like comparing the two that the A12 one has been milled down quite a bit.

I took pictures & tried to upload but I cant seem to get it to work right. I resized them & tried uploading but still no go. Ideas anyone?

what are the standard diameters of flywheels for these motors ? I thought they were the same diameter through the A series line, am I wrong?

Thanks, Evan
