| contd :- -2- Also when the pump is pulled on a cold morning with heavy oil, the oil will not flow into it out of the tank and one has to hold it out for about a minute before the charge enters. On the cold handle this is a painful operation, and most people will not do it. With plain front shackle pins an oil heavier than Mobiloil A.{Mr Adams} may be desirable in very hot weather to prevent the oil dripping out, but we have not found any trouble with it.
