Sparking Plugs. We have removed the Bosch W145T1 plugs from the inlet of 32 Ex. These plugs were missing fire on pick up. K.L.G.E.25 fitted cured this. The Bosch have completed 3307 miles without previous complaint, they have been returned to Mr. West for inspection. B.23.AE. Champion L88 have been removed from this car to make way for K.L.G.E.28. They have completed 2165 without complaint but appear to be running rather cool. Returned for repost. Rm{William Robotham - Chief Engineer}/WB.{Mr Brazier/Mr Bell} | ||
