Question: spark plug extension ????

Postby Glenn » Wed Sep 08, 2004 8:47 pm

The 1955 Cub has something that looks like some kind of extension for the spark plugs on cylinders 1 and 4, by extension; I mean a device that screws into the spark plug hole and then the plug into it. The effect is to raise the plug around 1 inch higher than normal, the device has a small hole in the bottom or combustion chamber end, I've never seen anything quite like it, what is it?????

Most of the time the cylinders were pumping oil and fouling the plugs out. These extentions were put on to prevent this.
Eight Cubs-finally got a '57.

Thanks Garvin, I really wondered what the heck those things were, they don't even look like they'd actually work.
