Changfa counterbalance shafts - R180 size

[veggie]

Anyone know if the R180 Changfa style engines have the internal
counterbalance shafts ? (and the straight cut gears that drive the shafts?)

I know the 185's, 190, 195, and larger units have the counter shafts, but what about units smaller than 185 ?

thanks,

Hey Veggie
I can only speak for my own RS180 Jeng Dong. No internal counter balance shafts. From pictures pretty easy to see if the manual crank handle socket is on the camshaft to the cylinder head side of the crankshaft for NO counterbalance shafts. Or if this crank handle socket is to the opposite rear of the crankshaft centerline on one of the balance shafts.
