Its a long shot but I have a Holley that has started to give me trouble. I cannot find any model information for it. On the choke horn the stamps read:
6170
1186
If anyone can help me out here I would greatly appreciate it.

Before posting this thread I did email 2 techs at holly.com but got no reply. I looked through every manual and listing I could find- nothing. After reading the responses here I decided to call Holley. Wow. Those dudes have incredible phone support. Within 3 minutes of dialing I had my model number and the guy is mailing me 4 items for my carb- for free! Yesterday I was looking online at different carburetors thinking I was going to finally switch. Not anymore, I am sold on their support.
Get the Advil ready... Hope you have a vacuum gauge, Webers are a true pain in the butt to balance and keep running right... They preform well, but a pain in the butt...
