hey i just got a 1980 4x4 hilux with an 1981 22r in it, runs pretty good so far although if i let it cool down for about 4 hours inbetween uses i have to idle it for a good 5-10 minutes or else it will die as soon as i give it throttle is this just something i have to live with?

it should not do that sounds like u need some carburator adjustments.

hmm ill try to work that out this weekend another question i have is my gas pedal is broken its connected to the floor and broken off of the throttle so it flips backwards while im driving. It also sometimes slides back and fourth because its broken making it hard to control the amount of gas i give it. I would like to remove it and just weld a new pedal on there but im having trouble removing the bolts from underneath the car that hold the pedal to the floor. Its a really tight space in there anyone have any ideas?

A drill a grinder or something else to remove the bolt all together. If your gas pedal is broken you should get that fixed before driving it more. I wish you luck on your carb problems too, I'm having my share of warm up problems too. My truck starts and idles ok for a few seconds then starts puffing white smoke then black smoke and will die. once I'm up to full operating temp it's fine and idles perfect with no smoke.

thanks for the suggestions

so i was tinkering with my carb today useing the haynes manual and it said before adjusting the carb screws adjust the idle speed. had to look up the stock idle for a 81 22r on the internet cause my hood has the idle speed for a 20r. anyway it said 700 rpms for a manual transmission. fired mine up it was idleing at about 1200 i turned the idle screw like 7 360 degree rotations to the left and that only brought it down to about 900 it wont go any lower the screw eventually just gets loose at about 12 turns. should i get my idle down to 700 before trying to tune the carb? and if so how?

another thing i have to do is reseal my valve cover its leaking, is there anything i should swap out or maintain thats sort of user friendly while i have the thing open?

I am having problems with my 22r carburator too. It starts and runs fine but untill it gets warmed up it puts out black smoke like crazy. It is running way too rich. The engine was blown and the truck was sitting for six years before I got it. Wondering if this might have somethig to do with it. I rebuilt the engine in 2012 so the engine is fine. Any help on this matter will help.

Well the usual problems with carbs this old is they often need to be cleaned, readjustged or rebuilt. If it has black smoke it's because it is running too rich. A can of carb cleaner can do a lot of good when used properly.

Running too rich is bad for the engine since it washes the oil on the cylinders, clogs catalysers which can cause blow-by and foul spark plugs. There can also be a lot of carbon build-up wich can cause pre-ignition, which is also bad for the engine. Not saying this is what caused the old engine to blow but too rich is definately not good.

Most will say ''just get a weber'', which is a good idea, but you can also rebuild your carb like highlux did: https://www.yotatech.com/forums/f197...97/index4.html

I don't think that the carb was acting up before the engine blew. The owner before me didn't change the oil (I knew because the oil had metal flakes in it) but the block was fine so no problems there. It might be probable that the long rest had dried the gaskets or something, I just don't know. I might get a weber but right now, I will try to fix the one it has. I have a new set of spark plugs. I will try to see if that reduces the smoke any. I will let you know. Thanks for the help Gillesdetrail

No prob, look at all the vacuum hoses, if they look old, replace all of them (one at a time) since its cheap insurance. Also get a can of carb cleaner and spray everywhere you can inside the carb and try to clean as much as possible, then replace spark plugs and see how it goes. Chances are it will run better.
