The gauge used for the 420s is T109-25.

Thank you for the correction... Interesting fact that it is the same tool used for the Carter (W1) 391-S... The T109-26 is used on the Carter WO carburetors, it seems...

We sold out of these (about 75 units) to the Jeep folks.
Someone has reproduced them somewhere, even to the Carter logo on the tool, and are being offered at ridiculously low prices.. Have not seen any of the repros, so cannot comment on the quality of this unit, but a lot of repro stuff like this is not overly great quality. This post information only, again, we are sold out of this tool.
