But why does it need to change its timing? As the engine rev’s increase the distributor advances it timing. Whichever you have the basic principle is the same. The 009 distributor is very popular with customers which have installed twin carburettors on their engine as it does not require a vacuum take off from the carburettor. Originally most engines were fitted with a Vacuum advanced distributor, but your engine could also be fitted with a centrifugal distributor with the most popular version being the 009 model. There are two types of distributors which can be fitted to your air-cooled VDub. If your timing is not correct then you will either end up with a nice spark but no fuel to ignite or a load of fuel and nothing to ignite it. So what we are trying to achieve is the correct timing that when the spark plug ‘sparks’ there is fuel to ignite and combust. At the end of each HT lead is a Spark Plug which ‘sparks’ when the voltage reaches its end. Position 1 and 2 go to the right hand cylinder head and position 3 and 4 go to the left cylinder head via more HT Leads. The distributor (as it names suggests) distributes the power in 1 of 4 directions. This 30,000 volts travels down the HT Lead (High Tension Lead) into the top of the distributor. This coil turns your 12 volts of power into 30’000 Volts of power (standard Bosch Blue Coil output). The SparkĪ spark is created by the ignition coil. From here the inlet valves open and allow the vapour to enter the combustion chamber of the cylinder head which is where the explosion (combustion) happens. This vapour then travels down the inlet manifold into the inlet ports on each cylinder head. The carburettor pulls in air and fuel and mixes it together to form a fuel vapour. In order for an engine to work it needs three things. So we thought we would show you how to time your engine correctly first time which fingers crossed will sort out your issues. It’s not always the timing that can cause one or more of these problems but it is a good start. Can you touch your dipstick once your engine has warmed up or does it burn your figure tips off? These are all signs that your engine timing is not quite correct. Maybe your engine is running a little hot. You might be suffering from a ‘flat spot’ in your engine rev range or your exhaust is coughing and spluttering. So you are having issues with your engine running efficiently.
