While rebuilding my carb, this assembly spontaneously, rapidly, explosively (kinda) decompressed and ended up in several loose pieces on my workbench. I have no good photographs on the details on how to get it back together. I have the attached photo that I took before disassembly, the blue circled part is the concern. There's a spring - in red - that I cannot seem to get in position to make the vent open and close properly with the throttle. I know these bowl vents are rare and most 2100s don't have them and as a result I'm having a difficult time with google trying to find out how to proper reassemble it.
Any help, photos, etc would be appreciated. - other than this issue and a resulting lack of power/hesitation/sputtering on accelleration from the throttle pump - my carb "throb" issue from before was fixed by the rebuild.
Thanks.
