Steve, I would think a disc would be alright, but they probably see stuff on a regular basis that makes them advise as they do!

Steve, I regularly use scotch write disc's to clean block. What Gunn does not want to affirm is that nothing can happen when doing this. When in fact it can, and real quick. Meaning one can take out metal, even with the green disc's if you stay to long in one spot. So if one always keeps the disc moving, and does even broad strokes. You should be fine.
I use thick paper cylinder plugs when I (and I have my apprentice trained in this as well). I vacuum or blow out the excess bits out of the cylinders, then clean the pistons with wire brush, and if the carbon is thick, a small screw driver to scrape the pistons lightly. Then when all is clean, I use oil around the cylinder walls to clean out the carbon. This way all the carbon gets out of the ring to cylinder wall interface.
I also wipe the pistons and cylinder wall off, so not too much oil remains.
Robbie

Thanks Robbie - great advice. I have been trying to keep the carbon chunks out of the cylinders, and clean as I go.

I presume when you use oil to remove carbon top top of the ring, what this means is that you dribble some oil around the pistons, and then crank the engine by hand, causing the carbon to stick to the cylinder walls, so that you can wipe it off?

if you're worried about taking any material off, what about the rubber finger rolocs? would they be better (safer)?

That's what I've always done, except I've used wheel bearing grease...6 of one 1/2 dozen of another.

If anyone sold the rubber finger Rolocs locally, I'd use them - but I will just go gently and quickly with the Scotchbrite pads. It's a cast iron tractor engine - I might be overthinking this.

Thanks, Ige - I tested the 'fine' grit HF disks this morning, and they seemed very aggressive/too aggressive. McCandless is right near my office - easy lunch run.
