[C320-list] Throttle

[Irving Grunes]

We had the same problem with 2001 #851
At the forward end of the engine that cable moves a throttle arm that
sometimes rusts up due to a minor leakage from the cooling system.
A good dose of WD-40 or similar and working it back and forth with the
throttle cable cleared it up for us.
