| N-W. EP. {G. Eric Platford - Chief Quality Engineer} Re. Carburation. With reference to your EP {G. Eric Platford - Chief Quality Engineer} /Thn10/H26.7.22, I will certainly take an opportunity of discussing this matter with you when I am next in Derby, but I am not quite sure when this will be, and in the meantime we are rather forced as to what to do to cure the trouble on these cars as we come across them. In fact, upto now we have had to allow cars to go although we have known that the carburation has not been correct. There is a certain engine speed when black smoke is emitted from the exhaust, and these are the cases where we have found the crude petrol in the port holes. We find these cylinders vary considerably, and in the engines where the trouble exists there is a distinct recess in the inlet port holes where petrol is able to lie. We are wondering if you have any method of filling up this recess and if so, we shall be glad to have the information at once. Br. {T. E. Bellringer - Repair Manager} | ||
