INDUCTION PIPES, CARBURETTER, ETC. You will notice that I favour this being exactly the same as "SS {S. Smith} " Phantom. Therefore as far as I can judge your LeC.2529. is the best, but possibly in going over it again you can finesse some little gains. I should favour LeC. 2527. length of boss so that head joint can be made with box key on all studs as you suggest (much better practice.) I cannot see why the same head will not do for new carburetter- underfed pipe - i.e. LeC.2531. (or with/R's sketch which we hope to have ready soon-) and why your underfed present carburetter should not be tried. R. {Sir Henry Royce} | ||
