well they don't have mpems...and the stators and flywheels are different. I do believe that you can use either engine with either ignitions but you need to swap the whole ignition out. Fly wheel, stator, and electrical box, needs to be complete.

yellow engine had all the "guts" inside/behind flywheel, where the hite motor, ebox, was on top of battery/left side of tank.

the cooling system is different as welll, the white, was more efficient.
