Toyota Repair: 22r carburator problem, electric fuel pump, vacuum lines

Question
I just picked up a super cheap 1979' 4x4 frame, 1980' short bed body, 22r powerd mutt. I dont know how to find what year the 22r is. but the carb has what i believe is an electric choke and another single black wire going to it along with more vacuum lines then i can count. The carb wires are not hooked up properly as I havent found any diagrams yet.
   The problem is it will start up but not idle. I have to run about 1/3 to 1/2 trottle to keep it running and it chuggs pretty bad, until upper rpms it smoothes out some but after 3-5 minutes it seems to flood. This is after i put a new mechanical fuel pump in because when i bought the truck it had an electric fuel pump mounted under the hood. the guy said his mechanical went out and he had the electric pump lying around so he used it. but it floods the carb if you leave it on so you have to turn it on and off in, 4 seconds on',10 seconds off increments. Thats how i got the truck the 80 miles home. It runs great as long as you dont push to much fuel into the carb, or let it empty. But its not so much fun to steer/shift/break/turn/and so on while flipping a toggle swicth every few seconds so it dosent stall. I replaced: plugs, wires, oil, oil filter, air filter, fuel filter and mechanical fuel pump and flushed the radiator since I brought it home two days ago. I would really appreciate any help. I know I dont have the money for a shop  to fix it. I usually fix my own vehicles problems but most of my vehicles are two wheeled and/ or fuel injected which I actually understand better then wiring on carbs.
Thank you in advance for your help.

Answer
I would start by replacing the mechanical pump. The current sintuation with the much higher flow electric pump is doing nothing more than greatly sacraficing ring life. (Grossly excess fuel washes oil off the cylinder walls.)

Once that's done you'll be getting a much closer to correct fuel mixture on the truck, and you'll be able to continue for there.


Toyota used those R blocks in about everything in the 80's. You can find them in basically anything at one point or another. From Celica Supra sports cars to trucks & SUV's. The last was a turbocharged 22r-te (EFI) before it was replaced with the VZ block v6's.
