To get the 'best' help in a forum, you should make one thread per problem. You now have 3 going on per problem.... Folks don't always see the other threads so don't know what the history is or what has been tried already or what you found 'broken'....
I have been cleaning and kitting carbs for years and haven't ever use a dip pot, I only have access to the spray carb cleaner usually. Be wary, there is a 'throttle body' cleaner as well as a 'carb' cleaner. They don't mix and match well, the TB cleaner won't work well on a carb and the carb cleaner will dissolve a TB.
First thought is the float level is way too high. well, it has to be to have gas pouring like you describe. Did you need to adjust it much? Usually they need very little adjustment. Did you have any issues putting the new float needle and seat in?
You also need to use two wrenches when putting on the gas line or you will mess up the float level pretty bad. The fitting in the carb has to be held from moving when the gas line gets tightened on but this usually makes the float too low so may not be any issue to you.
You have to be exact and kinda gentle when doing things like the vacuum piston adjustment and pump adjustment. The idle speed screw also 'has' to be backed off for this like the directions say.
I think the float is your whole issue at this point. There is also another way the idle mix screws don't work and that is if you get the carb baseplate spacer in upside down. It has notches that must be on the top side.
In one of your other threads you mention a broken dashpot. Do you mean the sol-vac unit? Sol-Vac
If so, it is only usually used for AC and an automatic and can be ignored. Did your idle linkage even have a screw that will hit on it?
One last thing regarding the gas running after a shutdown. Do you have the proper gas filter in it and is is sititng level with the center line to the carb and the top line to the return line? The return line needs to be at the top so on a hot shutdown the vapors released go back tothe tank via the return line rather than vapor lock the gas line by pushing all the gas out.
Then again a really high float level will allow it to dribble gas internally for a while.
