More minor changes are the generator has a shorter wire to plug it into the loom and the internal gearbox ratios are slightly different.


Gotcha, I assume this will be irrelevant if running premix? Or is it advisable to stick with the pump on the later models?

Other than that is it simply a case of switching the flywheels and swapping them over?
