    Exclamation Recycling plugs

    It was a long time ago in auto shop that the teacher showed us how to clean spark plugs.
    Well, I change them often and thought to get this handy little sanblaster to start recycling them.
    Am I wrong to do this? Is there any reason that people don't recycle plugs any more?
    Just curious.
    Thanks.
    Peter

    Hi Peter, well I guess it would depend on what media and size you are blasting with, and if the plugs are worn or have used up there service limits...
    If your to aggressive with the blast it could harm the procelin isolator...JMHO...PR...

    usually in the beginning of the summer when i want to fire my ski up, i'll pull the old plugs and hit them with a little break cleaner and wire wheel them a little to get them clean and to fire to make sure there are no problems. then i'll go get new ones. i change mine about every month in heavy useage. just cleaning them vs. new you notice a bit of performance loss. at least i doo.

    ^^^^^^^^^^^What he said, plus if you accidentally leave a single piece of media/sand in there - you're screwed. No thanks. For $1.49 each, twice a year, that's a whopping $6. You'll probably use that much money in cleaner and electricity running the air compressor. Not cost efficient IMO.

    I put new plugs at least once a year in every 2-stroke I have. Cheap insurance, and I keep the old ones around as spares in case one goes bad. They tend to do that sometimes for random to no reason at all.

    So am I being too picky by changing plugs each month? I figured that when I see carbon on them and oil that it's a good thing to put fresh ones in to get the hotest spark.
    A pair is a about $8.00 a hit here.

    Yes. The plugs will last an easy two years, even with fogging, if your carbs are set correctly. The ceramic electrode should only get chocolate brown...if it is getting black then it's too rich. The outer ring where the threads are will always be black...that is nothing to concern yourself with.

    I've run the same set of plugs over two years, running premix, turning 7550 rpms with no max rpm loss. If the plugs are carboned up there will be a max rpm loss.

    Another thing that will help performance and plug life is indexing your plugs. You'll get another 40-50 rpm just by indexing. You want the open end of the spark plug facing the exhaust port.

    This is the site that sold the indexing washers I use...
