I'm looking at purchasing a few cores for rebuilding an Autolite 4100.
Response from the seller says two of them are 1.12 and one is 1.19.
I never heard of 1.19 before, is it me or is it him?

The 1.19 were rarer, but real.------------------

Since the 1.08 were about 490 cfm, and the 1.12 were about 600, does that make the 1.19 more like a 715?[This message has been edited by Scott H (edited 12-31-2005).]

Here's a link on the 1.19. Sounds like you try to buy it!

How do you tell which you have? I have one but don't know how to what size it is. Spencer------------------

There is excellent info at www.ponycarburetors.com with photos to help you identify what kind you have, and also details of where to look for numbers.On the 4100 there will be a small circle about the size of a dime on the drivers side of the carb near the front. That will have the venturi size. Also on the left front toe where the mouting nut goes there should be a 5 digit number stamped on the side, something like C5AF-H.
