DEPARTMENTAL MEMO. This column is for Name of Person addressed. DATE. Mr. Wormald (Derby). 17-8-1912 Thank you for your letter of the 26th. ulto. and for enclosing copy of report from The Technical Department re knocking in Air Pump. Below I give a list of alterations, parts, etc. that are required on our cars out here, also an explanation why they are required. Some of these I have mentioned before. 1. FIBRE BUSHES. Fibre should not be used out in this country, if possible, as it contracts and expands to a great extent. When used as bushes in spring shackels and springs, it causes same to squeak after a car has run a few miles, however much they are oiled. Note :- Cars which we have fitted with P.B.bushes have not given any trouble. Fibre when used in connection with the "make and break" of a magneto often causes the "make and break" to stick up. Note :- Standard cars in Delhi had this trouble. 2. CARBURRETTER. We have found that we do not get such good results out of our cars when the carburettor gets too hot. If a hill is climbed say in 5 mins., when the water is at boiling point, the same hill can be climbed in less time if the carburettor is cooled down. It appears to me that the mixture becomes too weak when the carburettor is very hot. (Cont'd). This sheet must be filed with the correspondence to which it refers. | ||
