This motor was installed new last June. Ran it for a total of 4 months with Castor 927 @ 32:1. I tend to run a bit richer than maybe I have too.

Love it!. I use castor 927 across the board and it's been fantastic for me as well

Any suggestions on getting that carbon off? I just tried hosing it down with brake clean and attempted to scrap it off with flathead. Hoping it would flake.... It did not 
Scrape it off with an xacto knife

Easy off does wonders removing carbon. Used it on some full size but not sure what it would do to nikasil though? You’ll have to do some research. It will etch aluminum if left on too long!! It’s basically foamy caustic.
I had the same carbon build up but switched to Motul because we ice race in the winter and Castol doesn’t stay as well mixed below a certain temp.

I tried with a flatblad and started to scrtch it so I stopped. Got a new piston and ring on order so I got time to experiment with a soak.
Fair enough. I'll let it sit and soak in mineral spirits overnight and see what happens.
@MonsterAir i know what you mean, i did it very lighlty. But john parks idea is much better, im curious if a sonic cleaner could help as i remeber @Bizzer mentioned using one of them for the hobby.
I did my engine cases with mine when I blew my stocker 32, I haven’t ever tried it removing carbon but it might, as mine will heat up to 80 Celsius. Just can’t say conclusively as I haven’t done it.
This may be hard without physically removing it as there's really nothing that can chemically break carbon down in its purest form down without crushing it and emulsify in a solution as its still suspended in a solution its never really broke down.
And I Googled this

I have cleaned many LS pistons this way, always worked very well.

This carbon isn't elemental and will break down in a myriad of chemicals. Honestly I prefer the simple green in the ultrasonic cleaner method, but it will eventually break down with carb cleaner/mineral spirits like John said. Acetone does a pretty good job as well.

I gotta get me one of them ultrasonic cleaners.
Ultrasonic cleaners should be on every ones bench. They are so great for cleaning anything!

Any suggested units/brands? I see in the reviews noise level and actual wattage output seem to be popular gripes.
Mines just some offshore 
from flea bay, not a brand name. It’s gotta be 10 years old by now, but its loud as fek!!
This is basically what I have. Ultrasonic cleaner

Bought mine off Amazon. Closer you look, more they are all alike. Can’t go wrong with any of them. I bought a 4 litre unit.
