"Recently replaced the plastic
"Recently replaced the plastic float with a brass and along with the other internal parts in a Rochester Q-jet. Upon installation and first test It fired right away but soon stalled. There was fuel running into all four barrels. Disassembled and found that the float was set a little high, which would cause flooding. Reset using a digital caliper correctly leaking and it is a couple thousandths low if anything now. tried again and it ran much better, but I noticed that there was droplets of fuel dribbling out of the primary discharge nozzles even when the idle mixture needles are in all the way. Have disassembled a number of times to make sure that float is right and that the needle is free to set properly. Fuel level seem high so I made sure that the new seat was tight, it may have been a bit loose. Even with seat tight, needle seating correctly, mixture needles are in all the way, it still leaks and dripples. Any thoughts or suggestions. I don’t know how many more times I can take the top of the carb off without trashing the gasket.
Thanks in advance."
