We have so far made two short tests with this petrol and the results are not very good. Detonation is worse than usual and carburation is such that we have had to strengthen up the jets quite a lot to obtain the same results as on our standard fuel. However, we hope to make some exhaustive tests very soon and shall then be in a position to give a more detailed report. Mx.{John H Maddocks - Chief Proving Officer} | ||
