H Carburetor re-visited

(quoted from post at 09:10:27 09/04/11) I have IH D-10 carburetor on a '45 Farmall H that was a mess.

I have just cleaned and put a rebuild kit into it. Ironically the kit came without any instruction and am playing off the IH manual. I am real close to a startup once I change oil, filter and ignition stuff. Non-magneto.

An out-of-box first time adjustment as I remember is as follows:

Low idle ... is a no brain'er.... makes it idle nicely.

Top Jet (closest to the manifold) is the idle air mix. Bottom out the needle and back off to 1-1/2 turns.

Bottom Jet (base of the float bowl) is the high speed mix. Bottom out the needle and back off 2-1/2 to 3 turns.

Fine tuning would be under load and tweek the high speed mix so not to run too wet but still not stray too far away from your start point.

I know that these carb's are fairly forgiving for a first time run. I just want to assure myself I am still working within basic specification.

It is amazing how most of those kits come with no instructions, or if instructions ARE included they are the same as nothing. The H and M kits I sell are furnished with a full set of instructions including a parts break-down.

I will remember that when I do the SH next. That one has the Zenith carb and is about twice the size of this one I am working on here.

Thank you Rusty
