acceleration problem

Hi folks,
I have a 2005 Chinese quad that is a knockoff of the Yamaha Bruin or Bear Tracker. I bought it used with a couple of headaches that seem to be tied together. Here's the problem and what I've done:

1) wouldn't start with the electric start but would start with the 1st pull of the rope.
(replaced plug, drained and put in fresh gas) Started better with rope and would run fine and randomly shut off when you stop and be hard to start.
Bought a new chinese 250 cc ATV carb from ebay for about 50 bucks, installed it and it starts 1st pull and every now and then w/ the electric start.

Ran fine a while, now, after it warms up, it runs fine as long as you stay on the throttle, but when stopped is real hard to take off again for a few seconds. Backfires threw the carb and chokes out when you try to accelerate but takes off and runs fine until you stop and try to take off again.

Any suggestions on how I can get this thing dependable again would be appreciated.

Thanks, Dave
