Is it as easy as unscrewing the old one (when engine is cooled down) and screwing in a new one? Just got my NGK B5HS spark plug from spookytooth for my skyhawk 66cc.

NO not at all. The original plug comes with a screw on top on the plug. To install the original plug you remove the screw top exposing the threads. The replacement plug won't have a screw off top to expose the threads as you see on the original plug. If it should have, remove the screw top. The spark plug boot WILL NOT fit over the replacement plug without a screw top. As far as replaceing the plug itself, yes..off with old on with the new...

Where do you live that replacement plugs dont come with a screw top?

Seems pretty weird, they'd save about 5c and make it grossly inconvienient to use them (say, if broken down).. Unless I've misunderstood you..

But basically, if its tightly screwed in, and the plug fits, and (most importantly) it runs, then obviously you're fine.

I live in the good ole USA. Have been buying plugs for over twice your years. Go through this link and you WILL see two 2 cycle plugs. One has a threaded top that the cap screws off, the other is not to be removed, if you do you destroy the plug.

How do I go about this?

I can't believe this question. I guess I come from a time that at 21 you have already torn down engines and rebuilt them in a shop or your back yard. My honest opinion about your lack of engine knowledge and these engines don't mix. You really need a engine that is better built and doesn't need tinkering.

Now for your question. Take the plug and open the distance between the center electrode and the ground electrode to approx .050 this can be done with the tool pictured below. Then lightly tap the ground electrode almost closed (to about .010 to .020) . Now take the gap tool and insert it between the center electrode and the ground electrode at the thinest portion of the tool. Now rotate the tool or the plug until you are at the reading of .028 this will gap the plug to the correct setting. There are many tools that will do this, but this is not only the easiest but cheapest. They can be bought for around a buck at a Auto Zone, Advance, and 100's of other parts stores. Usually around the register as the plugs are behind the counter.

Sorry I sound so critical, but I came from a different age when boys were taught these things instead of having iPods crammed in their ears. This is where technology has done a disservice to this generation.
