Subject: LycomingEngines-List: Adjusting spark plug gap


I have the tool to measure the gaps and make the gap smaller - what are you using
to make the gap bigger?  I don't want to risk damaging the center electrode
or ceeramic.

I have some new plugs - fresh out of the box....their gaps are not consistent -
some as low .015 and some as high as .025.  I want to make them all the same.....


The plugs are UREM37BY and the outer electrodes go up then in (holding the plug
in your hand with the working end up - kinda like car plugs), as opposed to in
then up (which I've seen in pictures - not on my plane).

Thanks,
Ralph
