| Lillie Hall to W. /Rm.{William Robotham - Chief Engineer} x500a GWH{George W. Hancock - Head Chateauroux}1/L/20.3.36. 82 G V.{VIENNA} We had Mr. Fisher down here yesterday afternoon. He spent the time on the road with Roberts, changing jets. The final setting arrived at was .058 main jet, .036 by-pass. We do not say this is final until further running. We are still getting a hesitancy after the petrol is used from the effect of the pump. With the above jets 15 m.p.g. was obtained with an 100 mile run. There is a feeling that it is on the weak side for normal running. The starting up difficulty has been improved by taking out the union on the float chamber cover. Hs{Lord Ernest Hives - Chair}/G.W.
