Non-USA Carb and Jet ?'s

[71FJ40]

On the pre-9/72 Non-USA Carb, is there a HAC circuit?
High Altitude jets were not included behind the hex nuts under the fuel bowl sight glass.
Does anyone have recommendations for jet size above 7500 ft if the carb does not have HAC and the truck is always running rich

Also, where does one source jets?

no HAC. the oem toyota F engine manual shows 1.12 for the regular altitude primary main jet, and 1.08 as high altitude.

No different jet for secondary, but specifies a 2.00 for sec. main.

regular alt. power valve as 0.90 and high alt as 0.80

all diameters are mm, and to read jets remove decimal place, ie a 1.12 reads 112. sometimes the 1 is on the top and the following two numbers on the bottom:
1
0<- jet hole
12

Thank you - since the carb did not come with the spare jets I will need to order some and post the results

The usual sources do not even list a 1.08 - thoughts on a source??
