The basic function of a gas system is the liquid gas is stored in a tank under pressure. When the ignition is turned on and the toggle switch is switched to gas, a safety switch is energised by a pulse from the ignition system switching the gas solenoid on allowing gas to pass through the solenoid to the converter. The converter receives high pressure liquid and converts it to a low pressure gas, delivering it to a mixer. The mixer then mixes the air with the gas at the correct ratio as it enters through the carburettor and manifold.
THINGS TO LOOK FOR
The best gas system is the most reliable gas system. All gas systems require the cooling system to be in good condition as heater hoses are attached to the converter to prevent the converter from icing up. If it does ice up it could be a potential danger zone . An icy converter is a dangerous converter because the internal mechanisms may allow high pressure through the system if the converter becomes faulty.
IS IT EXPENSIVE TO REPAIR?
The converter is expensive. Unless it has a faulty diaphragm, it might be cheaper and faster to have a changeover converter than having it overhauled and repairing the items that are faulty.
TEMPORARY REPAIR AND LONG TERM REPLACEMENT
No temporary repair on gas. The only temporary repair is to turn it off if it’s faulty and run it on petrol until you get the gas fixed.
