I looked up the engine numbers, and they do not match The Ag has an SA engine, and yours has a B something engine. What that means I don't know.
If you have the AG engine it CAN be done but I am sure something will need to be changed... Mount? muffler? stator?..You can also buy a new QMB engine on fleabay or almost anywhere for under 300.00USD, and make the same changes... It is the same as the Agility engine.
