Questions about parts for a major service

Try putting the space heater on low or find an outlet that isn't on the same circuit. I have mine up exactly 20 inches, it really helps. If I'm on the roller it isn't enough to roll over though. I was hoping to go to 24 inches. I only don't like the first part of the jacking, one it is up i just go back and for a couple notches at time.

You removed the panel in the wheel well for the spark plugs...right? I'll admit unless on a 6 foot jack that engine most spark plug is a pain.
