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.
