Carburetor problems on a Troybilt sickle mower from 1990.

[Sandavidra67]

This is a 1990 model Troybilt sickle mower. It has been worked on by some very unskilled mechanics. I need to rebuild the carburetor linkage as it was all jury-rigged. I purchased a kit to rebuild it but the linkage was not included. One question I have is about the spring and the ring that it sits in. (Not sure the proper nomenclature of the part.) It is the spring that allows the gasket to function as the fuel pump. Does this spring and ring go on top of the gasket, or under it?

the parts circled below are the parts i need help with, Pump Diaphragm Spring and Cap Spring.

The spring and cap sits in a recess between the diaphragm and the carb body. the cap protects the diaphragm from the sharp edge of the spring so it side against the diaphragm.

And they come in the diaphragm kit from memory
I use the Stens or Rotary ones .
OEM had been discontinued AFAIK

Could you see it in your heart to post the engine model and type number? It make so much easier to look up the engine's IPL.

i apologize for the omission of the part number info:
Model: 114982
Type: 0184 01
Code: 90031628

Okay here is what you are needing info wise. This is from the service manual. The spring cap would next to the diaphragm so the spring don't the diaphragm.
