Help!!!
 

ive got a 2003 ltz400 racing fourwheeler. i drove it yesterday and it kept wanting to bog out like i wasnt getting any air,or not getting gas. i blew out the carb,and the gas tank(which PREVIOUS had a clog). now it wont fire at all. i have a clean air filter,new ngk sparkplug,and the carb is clean. also it has a very weak gas stream coming from the tank,could this be my problem??
