G'day Norm,
Yep the Honda motors probably outlast three mower bases.
My GXV 120 motors have the factory cast iron flywheel so not sure if they all mostly do but
the 4 hp would be more than enough for a 16 inch mower.
These engine must last decades with the cast iron bore ,probably a motor worth re-ringing.
Since I put the cast iron flywheel on my LPG mower it cuts like an 8 hp slasher and I never seen
another mower run so smooth at 3200 rpm
Cheers
Max.
