Re: Buying a Gypsy - some questions Hi fellas, I have come a long way since I last posted these queries on the forum and have been able to do certain bits of homework. I am answering to my own questions, for the benefit of other members who may find some info useful. Quote:

This is for the PCV (positive crankcase ventilation). This prevents hot air pressure built-up within the crankcase and connects to the Air filter (acts as air exhaust) and the intake manifold through a one way check valve (acts as air compensator) through a T-connection. Quote:

This line connects the intake manifold vacuum line to the distributor for timing advancement. At higher RPMs, the ignition has to be advanced (early sparks) for proper fuel combustion. This is achieved using a vacuum activated actuator to advance the distributor timing. Quote:

This is simply the fuel-cut solenoid switch. Shuts off the fuel supply in the carburettor and makes the engine stop. Quote:

During cranking, since a lot of current flows through the starter motor, the ignition coil doesn't receive enough voltage for a "good" spark production in the spark plugs. This additional switch in the starter motor solenoid bypasses the resistor (mounted on the ignition coil) and compensates for the lack of ignition coil primary voltage. After cranking is done, the current to the ignition coil flows through the resistor, as it normally does when the engine is running. Quote:

Aftermarket bushings, takes a while to fit these. Took a while to install it, but now the 4WD lever works like a charm. |
