I bought a carb adapter from Ken Lambert which has a fuel line nipple on it. In the pics on his website the line is hooked up to crank case pressure to work the diaphram. My fuel tank is back on the CG so I need the carb pump. I know I'm doing something wrong, I just don't know what.

Since I have got off the subject, Ill stop here and do a search about troubleshooting walbro carbs.
