To "Enginenut"

You gave reference to a blocked carburetor passage. When I rebuilt the carb. I replaced everything that came with the kit. Two springs,balls,accelerator pump and a gasket. It is a Rochester "B" carb. I bought a gallon of cleaner and after a good soak I reassembled it. Set the float per spec. etc... Are there any "plugs,knockouts" or secret passages I could have missed? I tinkered with it today and you can open the choke and it will crank but after a about ten seconds it shuts down or if you are quick enough you can pull the choke and keep it running. I looked in the service manual and cannot find anything that I think I may have missed.

Thanks,
JMH
