Heres the after pictire of the carb.
It went pretty well. I've rebuilt the holley on my C-10 many times, but this was the first rochester. Once you get past the linkages, it's pretty easy. And only one left over part!
It's for the fast idle or choke or something. The choke puller diaphram has a slow leak, so I just adjusted it to stay open, it's almost summer. When I find a replacement, I'll hook it back up.
Cost was $35 for the rebuild kit, so my total spent is now $116.50. That choke puller part is another $35 so I'll wait and see if I can get a good used one.
