Plugging the gap
By: Web Editor
As an impecunious RAF National Serviceman in the mid 1950s I was suckered in by the price of 3s-6d each for two new plugs for my Scott. I fitted them but didn’t get more than a few miles before I experienced ignition problems, which usually on a Scott are due to plug faults like whiskering.
I duly stopped and removed the plugs and it appeared that the gaps were a bit wide so I dipped into my pocket for the feeler gauges and went about re-setting the gaps but every time I tapped the outer electrode closer and inserted the feeler gauge again, the gap seemed to get wider, not smaller.
When I looked at the other end of the plug I saw that the terminal had risen out of the insulator. In fact the centre electrodes could be pushed up and down in the insulator – and these plugs were bought brand new that same day! Might be the right price at 3s-6d but the quality of the five shilling Lodge or KLG plugs I normally used made a lot more sense as those centre electrodes stayed put!
Wonder if I was alone in this or did others have similar problems?
