Wor.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} RG.{Mr Rowledge} DA.{Bernard Day - Chassis Design} X5080 R2/M12.3.27. PHANTOM AND 20 HP. RE.FILTERS. X.3701 X.8080 X.5080 I do not object to a lengthy trial of any promising filter, but I think gauze might be found to catch fluff better than a long slit formed by plates. Naturally one wonders how it is that after so many years we seem to have more trouble with the same low speed jet. Personally I have never had trouble. Is it because some of the recent people - new customers - do not know that if engine does not slow run nicely the low speed needle should be lifted, and the throttle opened for an instant, and all is clear? We have a trouble here, and a virtue, but if one only knows the disadvantages, and not the extreme ease at which it can be overcome, they naturally growl. Is it clear enough, and easy enough, to find in the instruction book? I do not remember, or ought we to fit a plate for this instead of something of less importance and value to our reputation?
