Are you guys pumping up the tank at the end of the filling session? The cline MUST have some starting pressure in the tank, or choking the engine will not draw any fuel. The cline folks told me on the phone to pump up the tank two or three more pump turns (manual pump) after the fuel squirts out the muffler pressure tap and the tap has been plugged. In other words, pump in the fuel, wait till it squirts out the muffler pressure tap, plug the tap, and then pump in about three more turns of fuel. Squeeze fuel line so it wont squirt out (unless you have a fueling valve), then plug the fuel inlet. After doing this for the first time, I choked the carb like normal, turned the engine over three times (I thought I would have to choke it that much) and it flooded the engine! I now just turn the engine over once, choked, and it starts every time.
