RINA, a freelance air cooled hit and miss engine - PART 6

摘要

The valve push rod is a length of 5/32in. MS square with a half-round disc silver-soldered at one end and tapped 8BA at the other end for an adjusting screw (fig 18). As shown in photo 39 (M.E. 4383, 30 July 2010) there is an adjustable catch plate made from 3/32in. thick plate (fig 19). The valve rocker arm dimensions need to be double-checked on the job (fig 20).
