Where does this spring go???

[Lrdrlker]

I have a 1977 Johnson 70 hp outboard 3 cylinder. I recently removed the carbs for a good cleani g and when I was finished I ended up with a spare spring, which I assume goes on the middle carb because the linkage runs off the middle carb. I've looked on the schematic and I can't even find the damn thing! Pictured below. Possibly related...I now have a backfire coming out the exhaust when I increase the rpms in gear. Any ideas? Thank you in advance.

Throttle link spring, part number 0314807. #54 on the intake manifold parts diagram ??

This spring holds the CHOKE flappers OPEN at full throttle.------Keeps them from fluttering.

Thank you! I'll try and figure out which way it goes. Cheers

Any idea where the straight end anchors to the choke linkage

 

[racerone]

It does NOT anchor anywhere.
