Hello, I don't know if this is the best forum for this, I have been doing some reading up on spark plugs and how to read them. I understand engine should be cut off clean at end of pass to get good look at plugs. I am a little worried about doing this, I have manual brakes so they won't be affected but can doing this harm the motor in any way or the trans going that fast and far with motor shut off? Also I have a question about those air/fuel mixture guages, do they react fast enough to get a reading in a 1/4 mile? o No: :3gears: :Comp: Tom W
