Your numbers don't look right.

 

yes, I know. are there any 1706 carbs? seems like only 1705 then 1708, maybe the guy misread it.

 

boy did he get the numbers screwed up
it is 17083226 0943 FKC

And it looks and feels like it is in very good shape

here is another one. I paid $9, this one on EBAY is $325!
Is there a market for rebuilt carbs, people got to be crazy to buy these shined up gadgets.

well this carb is an 800 cfm version

It is a poor shot but you can see the bump and venturi is large
