Sorry I forgot to answer about taking the carb apart...it has the blue gaskets...they didn't rip/tear. I just put the carb back together cuz i felt they looked good and didn't have any new ones kicking around. Bad me???
They are touted as non-stick but not necessarily reusable. I have ran into cases where I was able to reuse them but sometimes their crushed down to the point they just don't seal up very well again. One thing you can do that helps is apply a thin film of chap stick, Burt's bees, etc on both sides of the gaskets so they come off easier and don't tear up. I've reused them 2 or 3 times doing it that way. Check everything over good for vacuum leaks and make sure the accelerator pump is working properly like Rob said. Shouldn't be any play in the accelerator pump when you bump the throttle. Should squirt immediately. Like I mentioned above it's a good possibility you'll have to go bigger with the squirter and with a more aggressive pump cam to completely solve the flat spot and make it perform it's best.
