I have the carb dissassembled but am running into problems with the check ball and weight. The rebuild kit has a shorter and wider weight than what came out on dissassembly.The other check ball in the kitis too large to fit in the secondary pump inlet ,but i do have the one that came out. My question is Do I use the weight that came with the kit? Im going to have to use the the old ball out of the secondary passage so what is the other larger ball for?http://i7.photobucket.com/albums/y282/66fordstang/checkballandweight.jpg
