I went ahead and rebuilt the carb and glued in the intake with hylomar.
fired the bike up ready to go and the same crap, warms up and stumbles.
started to go through the manifold, the carb gasket looked real good.
I decided to put on a vac pump and check the VOES.
the voes wont hold a vaccum, i can get it to reach 5inches of mercury but it wont stay.
also found the vaccum line to the petcock had a hole.
so my question is this shouldnt the voes hold vaccum, not leak it off.
It will build up to 5-6 inches but then dropes off??????
thanks everyone for the help!
I do appreciate it...

Blob, it wasnt a very big hole at the 90 off the petcock, (but it still was a hole).
the vaccum pump could get the vacuum to 5 and 6 inch mark but would not hold.easy fix under a 100.00 bucks to fix, just have to wait for the parts to ship.

Any hole in the petcock hose is too much. Change that line.

any sort of hole in the vacuum line means that it's not making your voes work properly would be my guess, meaning that it's likely not holding enough vacuum to keep your petcock open.

fixed
I went through the carb cleaned and replaced seals.
the voes was replaced after waiting a week for it to come in at local HD store. (love these guys they always suggest I sell my bike and buy a new tc.)
Still had the idle problem, so after a few barley pops and thinking of that smart a@@ counter guy "you should get a newer bike".
Went through wiring and found the front cylinder plug wire to be bad and coroded socket on the coil.
After a couple more barley pops got it cleaned up and fixed the wire the bike runs pretty dam good.
Thanks everyone for your suggestions.

On the non-sarcastic note, glad you found the problem and didn't buy a bike off the showroom floor as suggested
