| S/W To Rm.{William Robotham - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} re Stromberg Carburetters and Flooding. I am not quite clear what the position is about this except that apparently these down draught carburetters flood when the car is on an incline. What I am interested to know is whether the same thing happens on American cars which use this form of carburetter. If not, why not, and if it does happen, how the Americans get over it. I see in one of Gry{Shadwell Grylls}'s memos. it says that Cadillac's and others are draining the lowest point of the down draught induction system by a pipe going down to the undertray and ending in a ball valve so that the mixture is not weakened for cold starting, but I imagine this must be something of recent development - otherwise presumably we should have known about it, i.e. seen it on American cars which we have bought or tried. I believe that, if the flooding does occur, it is dangerous because it flows straight into the engine. Sg.{Arthur F. Sidgreaves - MD} | ||
