Most BBD's suck too. My opinion is that all BBD's should be used for fish habitat at the bottom of the ocean... but I digress...

If you think you aren't getting all the fuel you are supposed to, double check your fuel lines from the tank to the carb. I had a tiny leak that showed no wet spot and offered no fumes, but was enough to defeat the pump. A few bucks worth of new lines, and never had the problem again!
