There hasarisen quite a controversy relative tothe proper manner in which to set thevalves. I claim that the proper meth-od is to set the high pressure line andline, thus giving the low pressure l/iof an inch lead. There are a number,however, who claim that the low pres-sure valves should be set line andline, claiming that when the valves areset in this manner that the engines givemuch more »atl»factory service.
