BTW ... a previous post about the six screws vs eight was oddly timely. I will now go back and remove the two ..

I have a 4776 double pumper and I have an odd problem. I have the 30 cc diaphrams and springs. When I prime the car to start by manually moving the throttle cable, the squirter off of the main bowl does nothing while the squirter for the secondary is on a hair trigger. I have swapped the diaphrams front to back... same thing withe springs. I even swapped out the metering block but still nothing. I have to literally push down very hard with my finger to get the squirter to eject fuel. I even swapped the squirters from one side to the other.. I am totally at a loss to understand what I am missing or what I need to do. Any ideas??
