Went for an evening drive in the Chummy which, to my surprise (considering that it ran perfectly a few days ago), started up on three cylinders. To see if it would clear, my 11-year grandson and I drove round the block; but the trouble persisted and so, arriving back after a few hundred yards downhill (on the overrun) to the house, parked up. Of course, on restarting the engine the accumulated, unburnt fuel in the exhaust ignited and with a suitable crack, flames poured from the exhaust - this to the great delight of Leo. The trouble was traced to No.4 plug, a 200-mile old NGK which Leo, without any encouragement, successfully removed. On testing, the plug was dead, not a "spark" of life..... so Leo put a new one in and off we went, one smiling boy at his achievement. His comment on seeing the engine? "Grandad, it's no bigger than a shopping bag!".
