Do nothing else until you get the cable off of it, you may fix something that isn't broken otherwise.

A direct drive is a 1:1 drive and is as I believe what most all Cat 30''s were equipped with.

I have a permanent starter button near the engine, it is hugely useful.
If the engine will start and run on a shot of ether, the problem is the fuel.
