I have a '77 Sout II with a 2 bbl holley carb. Problem is, the PO did an engine swat taking out a 304 and put in a 345. I also have no clue where to find the carb listed on the line setting ticket. So I'm wondering if there is a way to identify the model (whether it is a 2210, 2300, etc. ). Is there a way to identify the carb without pulling it off? FYI- I'm not real mechanically inclined, i know enough to ask the right questions most of the time, but don't have a lot of experience. Thanks for any responses.
You can tell just by looking at it. A 2300 will have a float bowl that is attached by 4 screws from the front of the carb. A 2210 is built different, the "top" comes off the carb and that is how you get to the internals. For this reason, 2300s are much eaiser to tune/service.
When I say top I mean the air horn. Look on the fuel bowl where it says holley. If it is attached in the corners by 4 screws then it is a 2300.
Look at the air horn: The part that sitcks up above the lip that holds the air filter. You will see several numbers stamped into the metal. Write those numbers down and take them to the parts house. They will get the correct kit for you.
For DEFINITIVE IH carb identification go to this link, you will find samples of ALL variations along with additional information. The LIST number on the Holley air horn, or main body defines exactly WHICH carb you are concerned with, and what It's OEM application is/was: http://www.ihonlynorth.com/forums/carb-tech/ Any other carb I.D. reference is VERY generic and does NOT include all possible "variations" which "might" have been OEM on IH crap. Oops! You must be the same "Dan" that emailed me yesterday??? I see the Utah connection!
