Engine flameout, uneven idling speed troubleshooting

Engine flameout digiprog 3 happens, speed phenomena for instance uneven or excessive speed should be timely symptomatic judge, inspection and exclusion.
1, idle flameout
After starting the engine, from low speed to high speed operates effectively, but stalled quickly after releasing the accelerator pedal; Or very first operating unstable, then turn off. This phenomenon might be determined as an idling-stop faults.
Idling-stop, the first determined by the actual situation around the idle adjustment (if clear the fault can also be directly repair). Adjustments, for instance the fault disappears, the idle screw is adjusted correctly; such failure can not disappear just after adjustment is often bigger throttle opening to preserve the engine is running, including with cotton or paper verify the carburetor, intake manifold gasket at no matter if leaks; if not leak, get rid of the pilot jet checks whilst blowing by way of idle oil channel, and after that re-installed trial; including the fault disappears, indicating pilot jet and idle oil duct blockage. For autos equipped with shut-off valve in the carburetor idle speed should also verify the closing solenoid coil circuit is standard. If it's caused resulting from the coil circuit just isn't regular idle fuel orifice blocked, the response to cut-off solenoid valve for repair.
2, idle instability
The engine fgtech v53 is not running smoothly at idle, the exhaust pipe issued a "sudden chatter, chatter sudden" sound, ordinarily idle instability failure.
Will stabilize at a specific engine speed and listen for leaks website. If tricky to ascertain the leak site, in the carburetor, coated with a tiny oil in the reduced liner, oil being sucked in to the leak is in the place, can liner fastening screws or subtraction technique excluded. Then adjust the screw into the throttle, increase the engine speed, and then gradually right after idle speed adjustment screws tightened to relax, to find out no matter whether the steady speed; throttle adjustment screw after which relax somewhat, gradually and progressively lower the engine speed and smooth operation, ie fan blades rotate evenly, can distinguish blade profile (400r/min). If adjustment is ineffective, then the view in the carburetor bore verify the oil, in the event the oil level is also low and need to be adjusted. Such as inspection are intact, should really continue to check the windshield wiper tube into the exhaust manifold for cracks and leaks spot. Unpack the carburetor with compressed air blowing via pilot jet and idle air hole, refitted just after such a good job, that is the amount of clogging.
If the idle speed just after the above still no improvement just after repair, the fault could be in the engine, generally the engine intake valve rod and conduit brought on by the gap is also significant, it may be close for the engine is overhauled, technical performance resulting from the decrease, which should really take away the cylinder cover overhaul.
3, the idle GM MDI speed is also high
Engine idle speed is larger than the regular range, and can not be decreased by adjusting it, this case is the idle speed is also higher failure.
Engine idle speed is too high, must be parked on a flat ground, pull the choke knob and hand speed push pull knob in the end to be checked. By hand throttle rocker, the throttle closed, when the idle speed is normal, then the carburetor lever spring is as well soft. Should you press the throttle rocker invalid, verify for loose throttle shaft or throttle shut tight. When the throttle is regular, then the application idle adjustment screw to adjust idle speed. If a good tune, that is the outcome in the original is not adjusted effectively. Adjust the idle speed is invalid, the view around the carburetor should remove the plug hole, to help keep the engine idling, if the gasoline from a manhole outflow, indicating that the oil level is as well high on account of the fault that may be excluded.
