I've got the Seloc Marine manual for Johnson/Evinrude outboards from 1973 to 1991. It says it covers all 60-235HP 3 cylinder, V4 and V6, 2 stroke models.
The tag on my outboard has a model of J75TLCTE, which the appendix says is a 1983 Johnson 75HP 3 cylinder with a type III carb.
If you flip to the section on type III carbs... it says this...
"Type III Carburetor with low speed orifice, intermediate speed orifice, and high speed orifice: All V4 and V6 powerheads 1979 and on EXCEPT 85HP 1980 only; also 115HP, 120HP, and 140HP - 1980 and on, 200HP and 225HP - 1986 and on."
If you flip back to page 4-9, it lists the types and the model years they used them... But it seems to ignore 1983. If you've got the manual check it out.
I was trying to help another member with his 120HP model, and found the same problem with a different model.
