Reply to "600 carb issue"

I removed both floats and check for leaks. Both passed and no damage noted on eather one of them. I thought that the secondary float may have been hitting the blank off plate with a secondary gasket installed, it wasn't on when I removed the bowl but showed it on the rebuild kit diagram. I removed it and there was no difference. I haven't gotten a pressure gauge yet though my vacuum gauge is suppose to be able to read the fuel pressure so I may try that next. The enitial vac was reading real low so I suspected a vac leak but after checking and spraying everything there were no leaks. After retiming and the second install of the carb I was right on the numbers, 18in. at the manifold. I thought about the fuel pressure but couldn't figure why one bowl was fluiding and the other lean. A new Fuel filter was installed as well. As soon as I made any float adjustment is when everything went south. I'm thinking the power valve is defective in the kit and ordered another for delivery today along with a new set of blue gaskets, the first set only lasts 3 times. It's like lots of fuel is getting to the secondary bowl but not the primary, checked the carb filter as well. Darn...
