Surely there wouldn't be big differences in the water channels on each side of the block? Anyway, fortunately on a motorbike with carbs this is easily accounted for by adjusting the jets/needles on each carby independently until neither runs rich.

Usually on bikes it's the clutch side that tends to run hotter.

Not one side of the engine, one side of the plug.
I presume its the side away from the inlet valve. Every time I have looked at my plugs in the 3 V8s I have owned, they have been white on one side of the insulator and sooty on the other side.

I take it that was before you moved to the Alice?
I'm trying to picture V8 ski boats competing in the Todd River Regatta. :p

for the plugs sooting on one side.......they are actually cleaned on one side from the fresh cold fuel charged hitting them.....
the cold wet fuel de-carbs that side of the plug........



as for the rangie.......could it simply be in limp mode......?
