| -3- Hs{Lord Ernest Hives - Chair}/Swdl.{Len H. Swindell}18/KW.4.12.35. (b) Silting of the Oil Metering Jets to the Plungers. Although now running with the latest .025" jet feed hole LeC.4633, which has replaced the original feed, an annular clearance, Hancock reports he still has trouble with stopping up of the oil feed. This he says is mostly due to fluff, presumably from the Tecalemit filter element. From this it is obviously necessary that we should, as soon as possible, have a design of fine mesh Auto-Kleen or gauze filter for trial on the tappets.
