The cranks for the propeller models are all the same size. if a prop crank is too small for it , then I would conclude that it is a Car Crankcase.

Hello,
You are talking about a crankcase not a crank, correct. Some time around '72 Cox stopped tapering the nose of the case. For the last couple years prior to that there were a couple different profiles, including a a 'fat' tapered case.

Travis,

I can never open up your darn pictures! lol!

From what I can see in the preview that crank and the crankcases are surely from a car/snowmobile application and the extra meat on the snout is made to withstand the rigors of a pull starter.

Also I seem to remember someone mentioning a pull starter on a Cox RTF. I could be wrong about that though.

The case on the left, (w/ the tapered shaft,) was used with recoil starters. The one on the right is the early version of the car crankcase. (Buick and Corvette.) This type used a stock Babe Bee crankshaft. Later versions had a beefed up crankshaft with larger splines for the flywheel.

Why is that? Some are viewable as is, some will open in a new window and others require that I zoom out to 50% in order to view the entire picture (at a reduced size and then I can't read the text No ).
