As long as I find a crank from a scrambler they are all the same from 65 to 68 for the 305 correct?

I have had CB77 con rods machine and sleeved, but the crank was split to do it. It had to come apart to clean out the hard crud in the oil slinger grooves and to be lightened.

I had a different shop machine a smaller Cb160 con rod - on the crank. They needed to support the crank and just clamped teh rod down fairly hard to stop it from moving. The same approach would work with a Bridgeport mill for a CL/CB 305 crank.

Cranks on CB's have an oil hole to lube the starter clutch, CL's have no hole.

Is it still possible to run a CB with the starter motor removed, even with that oil hole in the crankshaft?

Fill the hole in the end shaft or leave the starter sprocket with a good seal on the shaft. .........lm
