| -3- 153 report on what he did on the slipper wheel. 21-EX is better for piston knocks than the cars at Derby, but one piston is noisy when starting up. We have got an excellent example of servo squeaks and have cured it with a small dose of paraffin and oil. We shall now be able to ascertain how long the cure lasts. We have not yet tried the 19" wheels, but have them here. RHm | ||
