A friend of mine has a 22R that has a dying issue. It will sit in the driveway and idle all day long, but as soon as you get it on the road for 5 minutes or so, it wants to die, and won't start back up for 10 minutes or so. If I run it in the driveway for a while and raise the rpms to about 2500rpm, it will eventually die also. Any ideas would be helpful.

He said he's already replaced the fuel pump, plugs, and ignition coil. He said he did replace the carb a while back with one from another 22R. It has several of the vacuum ports soldered closed, never seen anyone do that before.

Working on it last night, pulled the carburetor off and checked the float adjustment, it was off by about 4mm too low. In the meantime, he took all the linkages off and didn't pay attention to how they came off !!!!!!!!!!!

If anyone could show me a video of how to properly install the linkages and that spring on them, I would be eternally grateful.
Thanks guys!!!

 

Search Youtube for 22r carburator. You'll find loads of videos on it.

Sounds like it is starving for fuel. There are 2 filters on a 22r. One is just outside the tank, under the bed attached to the frame. The other filter/strainer is located at the end of the pickup tube on your fuel pick up assembly in the tank. I have seen them get a coating or a crust built up around the filter/strainer that will cut down on the amount of fuel that can travel.

Copied from my thread.
Part number for a new intank filter is #77023-12050. On ebay it is called a TOYOTA FACTORY NIB FUEL FILTER SUCTION TUBE DIESEL. It was selling for $4.50 when I finally found it. I paid $15 at Toyota. (83 pg 8) This filter is for carburated trucks.


External 22r Filter.
I knew I had a picture of the factory filter somewhere. Ignore the wonderful wiring hack job.


Clogged internal filter.
The float was frozen solid. I put the rust dissolver on it and had it working in 2 minutes. I am really starting to like this brand over PB Blaster. Here it is frozen up with rust. Fuel filter is hard as a rock also.


Cleaned up.

 

DCmatt, I couldn't find any good videos that showed how to put those linkages back on. But in the meantime, I will try to look at those filters. Thanks!

 

My boyfriends truck has the exact same problem. Runs like a champ in the driveway and as soon as he gets down the road it bogs down. He thinks it has something to do with the carb. Is the build up on the filter/strainer a possible culprit?

 

A clogged filter can causes issues. If it has build up on it, in some cases, the build up is like a hard shell that will not let gas pass thru or just enough that it can idle but not pass enough pass at higher rpms. I would check/change the fuel filter first and then remove the fuel return line from the fuel pump, crank the motor and see how much fuel is passing thru. It will give you an idea if it is getting plenty of fuel or not. It is an easy test to give you an idea if fuel delivery is your problem or if it is in the carburetor.

A clogged filter or build up on the strainer is like trying to breath thru a straw. You are getting some air/fuel but not enough to function. How is the fuel pump?

 

Clogged fuel filter is to date the only thing to stop my truck. It crunk up and got me home after a few minutes but after putting a new filter in, it hasn't happened again. The ethanol in gas these days is doodoo and builds up. Hate to buy and run some fuel additive every tank but it helps every now and get. Also I did this trick someone on here posted recently, I just can't find a link to it, shamelessly misquoted: "open up the throttle and cover the carb with a rag, it will create a suction and break up any gunk in the carburetor" I tried it, it did help. Also I opened up the throttle wide open and shot some ether in there.
