Idling problem - Toyota KE70 Wagon 4KC 1982

[KE70WagonSWE]

I just wanted to share some insight in my problemsolving when buying i Toyota Corolla KE70 Wagon 1982.

When I bought the car it wouldn't start no matter what I did. So I took apart the carburetor and cleaned the main and secondary jets, as well as the crap that was in the idle nozzle and all the rest. Used cleaning spray and air. When I then mounted the carburettor it still did not want to go well, either at high or low speed. It just turned of.

The next day I examined the solenoid that turns the fuel supply to the carburetor on and of, it didnt react when I put the ignitionon, and it turned out that a fuse had blown. After this I could at least drive the car, but now it still wouldn't idle.

I took apartn the carburettor again and now I cleaned everything possible could. And then there with it again. The car ran better, but died after a while when I drove it on the road.

Then I then tried spraying starting gas on the intake where it connects to the cylinder head, I noticed that the car accelerated in revs. I could immediately ascertain that it could be the gasket between the cylinder head and manifold and intake that was not good.

I decided to replace the gasket, and once that was done the car ran much better, no problems at all at idle or high speed. It runs well in higher and lower gears.

So the experience I take with me is that it doesn't have to be just the carburettor that is at fault, but it can be a combination of things. In this case. Electrical failure, (fuse), crap in the carburettor and a broken gasket.
