testing sprak plugs

[Gamecock]

I suspect that I need to change the spark plugs on the used motor I just bought. How do I check these to see if they need to be replaced. Also, if not too much to ask, could someone explain it in layman's terms?

Just put in new plugs. For all the more it costs, it's not worth the test.

pull out the plugs. use a socket wrench. look for damage on the old plugs, they should be a light tan color if the engine is running right on four cycle engines, 2 cycle engines<br />tend to have more sooty coatings on the plugs due to the oil mixture. put old plugs in trash. install new plugs, they are cheap.
