Farmall H carb E-12 diagram

If someone out there has an exploded view page of the [b:4fa4ac4b8b]1946 Model H's E12 carbureto[/b:4fa4ac4b8b]r, sharing it would be appreciated. I am trying to identify a couple jets and parts and need the diagram for the correct names (e.g., a pressed-in orifice and a screw-in jet). The parts need to be removed and replaced, as well. I have found the carb kit but don't know about these 2 particular parts.

Thanks.

H is a E10. Air bleed is the near flush one and the broken one is the idle jet. You can find a picture and part list at the Case IH online parts site.
 
This might help… The full pages have come out poorly. E-mail is open in modern view if you want a pdf of those pages.

Okay, how would you suggest removing the idle jet; some mild heat and needle nose pliers? An easy out screw extractor?
 
If the jet is damaged beyond repair, you could try freezing it out. If you heat the brass screw-in jet it will expand, which will make it even tighter in the female thread of the carburettor housing. I would get a can of freeze spray and freeze the jet itself, avoiding freezing the body as much as possible. It may work free. If you have to drill it, you will be obliged to make certain to remove every last tiny piece of brass from the carburettor. Good luck.

As for the screw-in brass, I apply a little heat to the cast carburetor.
It seems like fuel varnish has them "glued" in and a little heat softens the varnish.
At least that's been my experience.

Click to expand...

Drill it out and retap the threads. I've done many that way. I don't remember the size of drill or tap off the top of my head.
 
Update on the broken idle jet: applied some heat to the cast iron exterior. Drilled into the jet with 1/16" drill, tapped in the easy-out and slowly backed the extractor and jet out. Yes, the threads had gunk/varnish on them. That was a close one! :shock:
