So the old Ford 300 engine in my snow cat. I started all the plugs in the spark plug holes and left the engine alone for 3-4 years. This weekend I unscrewed the spark plugs and the holes are rusty, new plugs do not want to go in easily.
i ordered a spark plug thread chaser.
How to I make sure that I get the tool in at the proper angle so I do not make the rusty hole worse?
