Okay, I can’t seem to get a PDF to post so you can see it here, but this link to it on my website will work. This is what the 1979 Chrysler looper 6/7.5 manual says on the assembly of the Walbro LMB 215 – while a different carb model from the earlier one you have Jim, I believe the instructions will help:

Here’s a photo of one of my LMBs assembled. The new replacement springs are included in Walbro kit K1-LMB (about $15.00 on-line) and don’t have the short "L" but are just straight – so you don’t see it hooking around the right-hand pin post in this photo:
I’d still like to know what the miserable spring is supposed to do – other than fly across your shop and get lost whenever you try to pull out the hinge pin…… 😳
