Under normal conditions, once the ignition is in position "on" and threaded toward the key starting point, the machine went on. However, in certain circumstances be otherwise. Indirect engine life and we must repeat several times mengulir contact to the starting point.
This condition is the beginning of less normal on electricity and machinery. And is often experienced car with fuel engines, especially those still using platinum ignition system.
Difficulty starting the engine as in the case above related to the problem of perfect or imperfect combustion. Perfect combustion will take place on condition: still good compression, fuel mixture - proper air, and the initial position or the ignition spark is still accurate and the sparks are still good. Marked blue flame at the tip spark plugs.
Many possibilities that causes the machine less fit. But at least there are three possibilities that could be the cause.
1. Fuel Mixture
Lack of accuracy, adequacy or accuracy, adequacy mixture of fuel and air, but could be due to the quality of fuel can also be caused by incorrect carburetor settings. Too tight / loose in the setting Idle Mixture Adjusting Screw (IMAS) in the carburetor. (On machines with injection systems, this usually occurs because the variable resistor settings are not appropriate.) Also can be caused by dirty fuel lines, fuel filter and air filter.
2. Compression
When the compression of the engines is lower than required, it will certainly complicate the occurrence of combustion. Practically difficult to machine life. Kekurangtepatan This could occur because of improper valve gap, there was wear and tear on the seat and valve head, a lot of carbon crust on the head and valve seat.
It could also be due to worn piston rings, cylinder wall wear, or cracked cylinder head gaskets. Damage to the above components can cause a compression leak so the pressure is low machine generated.
3. Ignition
Sparks are less robust and less precise can also cause the engine hard to live. This condition is usually triggered by a platinum worn, weak absorptive capacity of the condenser or because the value of the coil ignition coil resistance is high due to heat. If the components are still good can be caused by changing the initial ignition and platinum gap size has changed. Re-appropriate set of standards.
In addition, a weak spark and inappropriate can also be caused by high resistance spark plug wires and spark plug gap is too big.
Most riders squelch only when a case of a little hard living machine. Perhaps because the engine can still be turned on after the ignition is turned several times. In fact, if left to it is quite possible that the effects appear far worse: the battery worn out example.
Batteries can be worn out because of excessive use of electric current at start.
In addition to the battery worn out, in case of improper mixture (incomplete combustion) is the next obvious consequence is the reduced engine power and fuel consumption to be extravagant.
Actually, setting the engine combustion system that supports excellence can be maintained if the rider does not ignore the schedule of periodic engine tune up. Because, at this time will be setting-adjustment and inspection of engine components.
So, remember. Do not forget engine tune up periodically. In addition to convenience and security, from there minor problems will be prevented from growing.
