Crankshaft advice

[Alan]

Plenty of people are using shell bearings with splash cranks. My experience is that it’s ok as long as you get the oil warm before using full power, which is harder than you might think. Austin rods are ok up to about 5000 revs so unless you plan on exceeding that there’s no real need for new rods. I’d find a good set of undersized rods and get our good friend at Alba Austins to machine them. He is rather good at that sort of thing.
