Re-using spark plugs

[energy]

Perhaps a stupid question:

I think I may have set my spark plug gap wrong. Would it be unwise to re-fit them after removal? Will they still seal OK or are they shot once removed?

Thanks!

Mine needed setting to 1.0-1.1mm and as I now have a slightly lumpy idle and was in a rush when fitting I suspect I may have set one out of spec. Just wondering if the crush washer will no longer seal well after being refitted!

So they are Ok to refit... will do that tomorrow. If anyone thinks this is not a good idea please do post.

Thanks!

Thanks for your advice - I thought they might not seal properly once refitted or something!
