Use a dozen copper machine maintenance is not tight to do
The available blowing smoke check the carburetor of the oil channel is smooth. Especially oil, vacuum tube more carburetor, especially imported carburetor, usually with compressed air blowing through the carburetor cleaning, but in the end what oil or really really blowing through the air channel, the operator is difficult to judge, and the resulting phenomenon is also a lot of rework. It is very easy to make sure that each oil circuit or airway is unblocked by blowing smoke rules. For example, no idling carburetor, carburetor apart to wash and blow dry with air, blowing through, with a hose (such as the distributor vacuum advance tube) blowing smoke, first from the idle oil hole, and then to the idle air hole, the smoke from the carburetor idle mixture adjustment screw at the leak, not idle oil channels and air flow, or should be re checked until the smoke until the smoke.
The available blowing sealing smoke check valve and valve seat. The valve clean milled into the valve within the conduit, the hand or the right tools (such as a screwdriver rod) against the valve, and a puff of smoke, smoke have been washed to the intake manifold and exhaust manifold, mouth to mouth do not fit manifold leak principle. At the same time, watch whether there is smoke between the valve and the valve seat. If there is no smoke emitting, it shows that the valve is well sealed, otherwise it should be ground again. Check whether the airway is clear
As everyone knows smoking is harmful to health, but cigarettes in automobile and motorcycle repair has some magical effect, perhaps not many people know that. Cigarettes can be used not only to diagnose faults, but also to use them for temporary emergency response when conditions are limited or tasks are especially urgent.
Also, can also be checked by blowing smoke transmission, rear axle, steering gear on the shell of the vent and the engine crankcase gas one-way valve (PCV) is smooth, then given to repair or replacement according to the situation. If the above components are blocked, the internal pressure will be raised, which will lead to leakage of oil in the relevant parts.
