Dear Sir:

What is the make and model of your vehicle? Does it use the exact carburetor model in the picture?

If so, then it may not be broken, just improperly assembled.\

Bimetallic springs do not break easily. In fact I know of no circumstance in which I have ever seen one break.

Perhaps some parts have been lost during dismantling and re-assembly.

You may want to get a 2nd opinion before buying a new carb - expensive!

Hope this helps.
