I'd check to see if your secondary hose from your petcock is hooked up to the intake manifold. I'm pretty sure the way this works is that as the piston pumps up and down, it pushes & pulls on a diaghram inside the fuel petcock, in a sense creating a fuel pump. so when your try to rev it up, it's getting fuel starved. Just an educated guess. Hope this helps!

sounds like something still in the mainjet. Pull it out again and make sure all holes are clear. Your missing something there.

i was told to use guitar string to help clean out the jets, so you might want to try that.

I agree it sounds like jetting but i would be careful with what you clean the jets with. If you use a guitar string make sure it's nylon.
