On the other hand, we had a 4 wheeler flat at Burroughes of Bressingham that was driven by an old hand who treated it like a car. We never put a spanner on it except for regular servicing. M.O.T. time - adjust the brakes and go. He would come back from the post M.O.T. trip complaining that it was going too fast. We hadn’t touched the pump, just driven it at more than 30mph and blown the cobwebs out of it. Whoever ended up with that Mercury got the bargain of the century. Jim.
