I was trying to rebuild my Carter-Weber carb but having a very difficult time finding a rebuild kit, I did find one for $175. I guess the problem is the unique accelerator pump. I have tried at lot of vendors, Walker, Royze, Summit and many more. 
  
Does anyone have a source for the accelerator pump, or have a carburetor they want to sell? 
  
This is an Arizona Brat, it was sitting for a long time and the pump dried out, soaked the pump in WD 40 for a couple of days, the diaphragm is now flexible but some of the rubber coating is gone. 
  
Has anyone modified a Carter VF pump to work on the 82 Brat?  
  
Any suggestions????
