- the atomized fuel stream may have an irregular shape;
- the nozzle jet does not close when the switch motor re-causes the engine to flood at start;
- the atomizer jet filter may be clogged, supplying fuel in smaller portions than required;
- seal may be damaged (breathable).
2. For inspection, the nozzle must be removed.
3. Check the condition of the rubber gasket and, if it has traces of cracks, crimps, it must be replaced with a new one.
If the gasket is damaged, the rest of the injector gaskets must be checked, as they may be in the same condition.
4. Special tooling is required to thoroughly check the injector. However, a basic check can be performed using the following description.
5. Plug the nozzle location hole in the head, and hold the nozzle in the corresponding glass cylinder. Start the engine and let it idle on three cylinders. Observe the shape of the atomized fuel stream. The atomized fuel must be in the form of a symmetrical cone. If it's not. the nozzle must be replaced because the vibrator rod is damaged or the spring is broken. Turn off the engine and wait 15 seconds. No fuel should leak or seep from the atomizer jet. If fuel leaks from the jet, the injector must be replaced with a new one, as fuel that leaks can flood the engine and make it difficult to start the engine.
6. The nozzle must not be disassembled for cleaning purposes. If the nozzle is removed from the nozzle, a new one must be installed in its place, and the connection must be compressed with a certain moment.
7. The gasket installed before installing the nozzle must be lubricated with gasoline.
