The green gasket looks good - not so sure about the grey one. The insulator looks good, but be sure you put it on the right way around so that the groove in it matches the port in the carburetor flange.
Most people who get poor results from cleaning those carburetors make one of three simple mistakes:
1. They don't use carburetor cleaner on the main jet because they think it looks clean. Blow carburetor cleaner cleaner under pressure though the jet: it is often reduced in size by gum.
2. They aren't nearly careful enough cleaning the emulsifier. Don't just blow carb cleaner through the central orifice: put a finger over the hole in the far end and make that carb cleaner squirt out under pressure from every one of the lateral holes. If any of them doesn't squirt or looks a bit less strong than the others, put a jet drill through the hole backwards, or use a piece of copper wire and a lot of care.
3. They don't clean the idle jet properly. The hole in it is tiny, only 0.014". If carb cleaner doesn't come out of the tiny hole strongly when you put a finger over one end of the lateral hole and squirt the cleaner in through the other end, you need to use a jet drill (usually 0.33 mm, but you use the 0.3 mm one that comes in the set). Note that in your case the symptoms don't match an obstructed idle jet, so it isn't a big issue, but it's never too early to develop good habits.
