ok no more shocks, no more water in the fuel and a very strong idle at 750 rpms. but the problem im still having is a very bad stumble if I get on the accelerator from anything after idle. sitting at a stop sign and then punching it there is no problem, but say im doing 15 to 20 miles per hour and then punch it it falls on its face. after a few seconds of very bad stumble it clears up and goes down the road like nothing was ever wrong. I've got a brand new holley 650 double pumper on it and the truck is timed at 14 degrees advance initial. the pump shot is set where it was when the carb left the factory. I'm thinking that when I open it up it is either running too rich or too lean. anybody have any suggestions??

thanks in advance.
