Yes, logical, but I usually take a hacksaw and cut a slot in one end 
of the rod parallel to the flaps. Not only is this permanent, but it 
also allows you to stick a screwdriver in there and tweak it slightly 
to make sure that it still moves freely. Sorry, I should have just 
cut that slot before I shipped you the parts. I just didn't think 
about it at that point.

The spring should be stretched. The rear end attaches next to the 
operating rod, while the front end hooks over the pivot for the BELL 
CRANK. Is it possible that you have attached it to the clamp at the 
other end of the same operating rod? The purpose of the spring is to 
take play out of the system and eliminate rattle that would 
eventually cause parts to wear out.

Yes, it's supposed to be warm in there. The tough part is that this 
is very subjective.
