monojet i6 drinking gallons at idle

[cartercarbaficion]

just picked this rusty girl up for free. nice little halfton only missing the outer rocker and drivers floor. other than that its very very solid.
anywho the reason im here is twofold, one it drinks a gallon of fuel idling in about 2 minutes which is insane and tells me theres something wrong with the carb or fuel system (not sure which since it came with 12 single barrel carbs in various states of rot.) the v8 pump installed is wrong and doesnt pull fuel more than about 3 feet behind it not sure about the pressure
2nd problem is i cant find the right rebuild kit or even a properly fitting air filter, ive seen more monojets without filters than with them at this point (i do have a weird bulky one barrel that fits a normal style v8 filter. i was debating on using my spare fiero air cleaner for the truck but it needs to run first)
any guides on rebuilding a monojet properly or where to find a kit that fits one
i do have an eventual plan for this truck that involves a 4wd suburban i picked up for free and im debating on keeping the i6 with the overdrive automatic or not.

did some work on the truck and realized the frame is just wrong. it looks like the suburbans frame which is a 3/4... but this has 1/2 ton springs and hubs so i think this is a hodge podge of a few different years of squarebody. the main ones being a rolled 84s drivetrain and frame and a 77s body and a early dual tank short bed

I got a rebuild kit for the monojet on my dad’s ‘76 250 I6 at Napa. They had it in stock.

If these flood, they will kill the engine and fuel will overflow the carburetor. Have you checked to see if fuel is going into the crankcase?

Probably a stuck or dropped float. Sometimes the float will crack and fill up inside and fall open needle.

You might want to reach out to Tom at www.12bolt.com and see if he has a good carburetor in his stash.

And I would recommend against running the engine until you fix that fuel issue as it is fuel washing the inside of the engine and most likely filling the crankcase with fuel, which is bad.
