Dang it, lost the Tech sheet...

My FSM says 1 3/32" float level adjustment and 1 7/8" float drop without emission controls. 1 5/32" float level and 1 7/8" float drop with emissions. Does not specify plastic or brass float.
Meh. Just posting what is in the spec sheet that I have. Can take a pic if you like.
Not surprising there are variations in aftermarket rebuild kits.

Once this gets hashed out, let's sticky this. I think it would provide good reference.

 

When I get home from work tomorrow I'll take a pic of the spec sheet and FSM info I have. Too exhausted tonight.
Something is not matching on our info though.
I used those specs to rebuild my Daughter's 2g and it runs excellent with no issues.
I've rebuilt many of them before but been too many years to remember what the specs were. I know I went off the rebuild kit or FSM info though. If used heavy off road I typically dropped the float level about1/32" to 2/32" for less flooding issues at severe angles and had good luck with that. If strictly street driven I had always set them to the recommended specs with a stock engine.

There are a total of 3 CJ publications that provide Rochester carburetor specifications.
I have those publications and two Rochester 2 GC's in original condition.
Note: the brass type float preceded the plastic floats.

I fully expect that the Rochester #7026082 should have a brass type float.
My Rochester # 7026086 has a brass type float.
My Rochester # 7026089 has a plastic type float.
I fully expect that the Rochester #7027082 should have a plastic type float.

The 1965 SM 1002 R5 SUPPLIMENT (72 pages) was issued in 1965 for Dauntless CJ's.
This manual provides the correct specififications and pictures the early brass float.
To adjust float level the Rochester air horn is inverted with the fuel well gasket in position.
.594 (19/32) float level is measured to the sharp edge at center line of the float.
The float drop is measured with air horn in upright position.
1-29/32" float drop measured from air horn to bottom of the brass float.

Both the SM 1038 and the SM 1046 provide the same information.
This information is for the plastic type floats.
1-3/32 float level with 1-7/8" float drop without emissions.
1-5/32 float level with 1-7/8" float drop with emissions.

 

Yes Patrick, I vaugly recall that exchange.
The SM 1046 was the final Universal Service Manual publication covering the CJ-3B and early CJ-5, CJ-6 models.
The SM 1046 was initially published in 1970 but only a very few copies were ever produced.
It was published in mass quantity in 8/71 and it was reproduced in 73, 75, and 77.
The 1975 and 1977 dated publications of the SM 1046 have cheaper quality paper and pics.
Overall the 8/71 publication of the SM 1046 is the best manual covering the Dauntless era CJ's.
But as you can see other older Willys, Motors and Kaiser publications retain some merit.

 

FWIW I finally got pics of my Echlin instruction sheet and from my FSM. I'd have to check and see what version it is.
