I have a 1969 Beetle That is having idle issues. I have gave it pretty much a full tune up, New Carb, replaced the parts in the Distributor, changed all the sparks and the spark cables and despite all my efforts it still will not idle. 

 

Does anybody have ANY suggestions for me??

Has the car been stored? Did you change the gas? Could there be rust in the tank? Maybe you've got a clog somewhere...

It was stored for a few years. Tomorrow I'm emptying the Gas tank and cleaning it and replacing all the fuel lines. 

Other then that what should i check? Already checked for a vacuum leak on the intake.

You mentioned NEW carburetor, did you check to see if the electric shutoff valve was working? I have a 68 and a 74 using 31 pic carbs, I cut the plungers off both and screwed them back in. After I had an engine fire in my 74, I relocated my fuel filter under the car by the fuel tank, installed a steel fuel line around the left side on the engine and removed that shutoff switch wire.

I have the same issue on a recent purchase. All new parts-tune up related. car runs well but smells fuel rich. I wasn't getting enough fuel and couldn't locate a pinched fuel line. So a buddy recommended a low p.s.i. fuel pump to boost my brand new stock one. It worked like a champ until the bug gets warmed up. then I have to floor it to start it. I also have to keep very little weight on the gas to keep her idling.  I called the place I bought the carburetor from-he said I need a fuel pump with a regulator for another $67.00 instead of a warranty on the carburetor. I went back to stock fuel pump alone and still getting too much fuel.....Help??

A simple way is while the car is running is to pull the wire out of the coil and look down the throat of the carb, right when it shuts off, if you see fuel running down this means the float valve is bad or fuel is leaking around the float valve, this can be fixed by putting teflon tape around the valve or replacing it, the carbs are made from pot metal not aluminum and the metal has a tendency to expand, flake and crack with heat and age, now the other thing is both my 68 and 74 came with 34 pic 3 carbs, I had all kind of issues until I went to 31 pic 3 carbs instead, now the only problems are the accelerator pumps failing due to the crappy ethanol in the gas, worse yet the replacement pumps are so thin, they don't hold up like the originals.
