| HS{Lord Ernest Hives - Chair}/FD.{Frank Dodd - Bodies}10/JH.6.4.36. 36-KX at Brooklands. A series of tests have been carried out at Brooklands on the Ph.III with Stromberg carburetter fitted to determine the petrol starving point, and arrange for sufficient supply of petrol to overcome the trouble. The following table shows the progress with needles and passages altered to increase the flow. Test 1 Pumps, flex, filter, RR. pipe line in the V carb. union, .312" bore, 80° needle, .180" seating. Result - starving. Test 2 Pumps, flex, filter, RR. pipe line in the V carb. union, .312" bore, 80° needle, .200" seating. Lap speed - 85.87 m.p.h. 1/4 mile " - 90.00 m.p.h. Result,- starving slightly. Test 3 Pumps, flex, filter, RR. pipe line in the V carb. union, .312" bore, 90° needle, .200" seating. Lap speed - 87.38 m.p.h. 1/4 mile - 92.31 m.p.h. | ||
