It is true to say that, no matter how fine, how fast or how rapid on long runs a car may be, it is worthless to its owner if he is unable to start the engine. Having suffered what we consider to be more than our fair share of difficulty in this direction, we recently had a Runbaken “Oil-Coil” fitted to the aged Austin Seven which serves as Editorial hack transport. This, in conjunction with a set of Lodge plugs, provides a certain start on the coldest and dampest mornings, even though the Exide battery has done over three and a half years’ hard labour with much abuse. Apart from providing easy starting, a high-duty coil maintains efficient sparking at the sort of upper rev.-limit in which sports-car owners indulge. Greater economy is also possible, but only if the plug points are opened out to cope with the ignition of weak mixtures and if the carburetter jets are reduced in size — it is remarkable how many complaints we get that people have fitted an oil-coil, opened out the points, but have found no improvement in economy. The fact is, they have omitted to reduce their jet sizes.
From the foregoing, it will be gathered that we regard the Runbaken “Oil-Coil” as a good thing. Interesting details about it are available from Runbaken Ltd., Manchester, 2.
