Picked up an old '78 kl250 about a month ago that had been sitting in a guys garage for a couple years. Thanks to a lot of good threads on Thumper I was able to find out a good deal about some issues I was having getting this thing going. One little problem remains before I can get this bike out and about. For whatever reason when I throttle up the fuel is running straight through the carb and then running out to the ground via the overflow tube. A couple things i've already checked. 1. The float is actually floating 2. the needle isn't seized and seems to be working fine with the float when i take it apart. WHAT AM I MISSING? Thanks for an help guys.
