1989 175 Jet/Orifice Question?

[crashkaloop]

I am pretty confused about the jets in my engine.

This part diagram for my carb shows item #3, which has three different options, with three different parts.


#3 ? 320015 ? ORIFICE, IDLE AIR BLEED, 150, NO. 33 (2 required per assembly)

#3 ? 323703 ? ORIFICE, IDLE AIR BLEED, NO. 36,175, MIDDLE & LOWER (2 required per assembly)

#3 ? 318823 ? ORIFICE, IDLE AIR BLEED NO. 31, 175, UPPER (1 required per assembly)

Now, my engine has two of these jets in the throat of the carb, and they are both #36.

My assumption is that the first jet listed above is for a 150 HP engine, and that the second listed above is what I currently have. But what is the third listing above? I do not have this jet/orifice that I can tell.

I am asking this because I am trying to configure my carb to run well at 5,000 foot altitude, and need to know what all the jetting options are. I think I need to go larger on my idle air bleed orifice, because it is very rich right now, and the plugs are soaked. I am OK on the high speed and idle jets, but this air orifice has me stumped because of the options they show.

Thanks for the help.

Ahhhhhhh, now I get it. I just could not figure out why there was only one required. I never would have assumed a misprint, as I am almost always the one who makes the mistake. Thanks!
