Re Induction Pipes.

Dear Hives

I don't want Dorris' paper on his induction pipes to make you think that we are of another mind on the question of the ideal shape of pipe. From his description, he collected liquid gasoline or kerosene, in all the bends, and though he says nothing about it, probably collected more in the bends nearer the centre, where the gas flopped in as it left the T. His first pipe with upward bends was no good because as you have found, the greater part of the liquid gas would never get near the hot spot but would be whisked off to either side, hugging the lower side of the pipe & getting into 1 & 6. Hence probably his experi-ments with bottles at either end.

The Stevens Duryea pipe as now designed with Stromberg carburetter, seems good. It is in aluminium thus:-
