Ok, so I found the vid on youtube. It starts and idles, but as soon as you give it gas, it falls on it's face. The jets are clean.
Here's kinda how that carb works. When you give it throttle, the upper diaphram acts off the vaccuum of the motor, and pulls the needle upward. That needle is the one that goes into the cylinder that the main jet screws into. The one you just took apart. If that needle does not move up, then fuel would not be allowed to come up thru the main jet, and it would fall on it's face like that. I would make sure that its put back together properly - the needle should move upward with that diaphram and I would also make sure the diaphram does not have any holes or tears in it. Also, make sure when you put it back together that the top cap seals the diaphram down correctly.
