I cleaned and polished the parts and sent them Mark Boesen for anodizing. He nailed the color I wanted and sent them back post-haste. The result was two engines that I think turned out okay. I have no intention to run the engines. These were more for show and fun. Besides, except for the extensions, they’re just stock engines.

Why are they low on comp?

wow running really rich or what?

nitroairplane wrote:Some claim the method doesn't work.
Heat the piston in a kiln then let it cool in air.
Some also do this then rapidly cool it in used motor oil.
Once this is done the piston will be very slightly larger.
Put it back in the cylinder with toothpaste and a suitable oil.
turn the engine over until it feels smoother than at first pr until it feel smooth enough to you.
This is a method I use and am NOT claiming it will definitely work for you.

No I did not have it that long
They just last long on good fuel if you treat them well.

That's just to get a good fit, it is an old trick that works great.
