Default Near nitro engine death experience

As the title says, my engine came close to death or so I thought. I decided to do some porting on the sleeve and the crankshaft that I read in a magazine. I didn't have as many ports as the article's engine had. After finishing on grinding and polishing, I cleaned all parts and used mystery oil to assemble the engine. I installed the engine and tried to run it. It acted like it wanted to start but wouldn't. If it did, it would only run for 2 seconds max. I thought I screwed up the engine by doing the mods to the sleeve and crank. But it would start only if I dropped about 3 or 4 drops of fuel in the carb and then die. So I thought I have a fuel delivery problem. So I started with the tank, fuel lines, and filters. I know I didn't have any air leaks in the engine since I used rtv silicone putting it back together. But luckily I had a new spare engine and swapped the carbs and it fired up and ran. It was running way rich. My table is covered in oil. But that's ok, at least it ran! It's ALIVE!!!!
I have ran about 10 tanks of fuel through the engine so I know it is broken in. I can't really feel any pinch in the piston/sleeve. But it has some very good compression and runs great.

Now my question is, how do I pull the old carb apart and see what the problem is?
How do I pull the sleeve out of it? It is a rotary carb.
