I rebuilt a friend's FJ40 carb a few months back and Hanes/Chiltons and the instructions included with the kit all had the float spec wrong. At what they suggested, the float never closed. It took a few tries to get it adjusted right. Worth checking. Also, with the carb top off try blowing into the fuel inlet gently to make sure the float is actually seating the needle, and there isn't some defect stopping it from sealing.

The only other thing I can think of is too much fuel pressure, if it's too high it will blow past the seat. Your gauge and regulator seem to rule that out.

Your pickup just started doing this randomly one day without having touched anything prior?

Thanks for the advice! I'll try lowering the float.

I purchased it from the previous owner behaving this way. Apparently he got it from a friend behaving this way.

The dude I bought it from did head gasket, new distributor, wires, plugs, fuel pump, filter, and a few other random things before throwing in the towel. He told me he pretty much narrowed it down to the carb and a rebuild would probably fix it. Rebuild did not fix it.

Worst case, if I can't figure this out, I'm gunna rip all the stock stuff out and go Offy intake + Weber 32/36. I'd just really like to get it running as stock, especially after all the work I put into the carb.

'86 Pickup w/ 22r - Starts fine after sitting a couple days, and runs great for about 3-4 seconds, then runs rough, sputters, and dies after about 10-12 seconds. I can keep it running by adding throttle, but again, would run very rough, and very rich.

Put camera on carb and could see gas filling up ALL THE WAY up in sight window, past viewable area, then sputter and die.

Rebuilt carb, new gaskets, jets, spent hours cleaning everything....new float, new float fuel cut needle thingy, adjusted float to spec (48mm and just under 10mm). Fuel cut solenoid clicks when hooked up but white wire doesn't do to ground, connected white direct to batt neg, now solenoid clicks on with IGN.

Played with all the adjust screws, minor differences in the way it runs, but sputtering/dying problem isn't affected.

Reinstalled carb + replaced lotsa vacuum lines for good measure.....SAME EXACT PROBLEM! Float bowl fills up past sight window very quick, then truck sputters and dies unless I keep applying throttle, which keeps it alive, but running very rough and rich.

Fuel pressure gauge + regulator installed. Reading about 4psi while running. Never overflows with gas, no leaks detected, just fills way too high. Maybe I need to set the float way lower for some reason? Even if it works, that seems like a work around that wouldn't be addressing the actual problem.

Any ideas? Resoldered the stupid grey ECC computer for good measure, but it seems like an issue with the carb itself? Or vacuum line? Isn't that float/needle supposed to cut all fuel going into the bowl? How else would it be getting in there?!

Just took this video ( https://www.youtube.com/watch?v=UhItywSiWy0 ) showing what's going on. I'm keeping my foot slightly on the throttle pretty much the whole time, you can hear it try to die the couple times I let it up. Also, it's running VERY rich this whole time....lotsa white smoke coming out tailpipe (no catalytic on this truck BTW, it's been straight piped).

Thanks fellas!

The green weenies are one of the most ignorant and delusional morons to walk the Earth.

We are rapidly running out of natural elements.  Batteries and solar panels may be future fossils.

One that cannot be artificially created is helium. It's predicted we will run out in 25 to 30 years... OH OH!!! bye bye cell phones. 

Helium is found in natural gas deposits.

Without helium many technologies, industries, scientific research, and medical uses will shut down or disappear.

Back to the good ol' days!! 

Gnarls.

Please read everything and let me know if you have any questions.
