Toyota Repair: 85 tercel, intake manifold gasket, vacuum leaks

Question
QUESTION: Hi. I have an '85 tercel that is new to me. It tries to and has stalled on me after
driving it for 10-15 mins. It is like the idolling goes really low and bogs out.  
Have adjusted the timing and it still does the same thing.

ANSWER: These cars had lots of problems with carburetors, how long have you owned this car?

QUESTION: i have had the car for 3 weeks now. We have put carb and choke cleaner through
it but nothing has changed.  Sometimes I have no real power go from a stop
then accelerating, other times its first off the line as well

Answer
There were a couple of chronic problems related to this issue, the carburetor itself which was a poor design, the base of the carburetor gasket leaking or the intake manifold gasket leaking, all three of these can cause vacuum leaks which will cause the kind of problem you are having, I have no easy solution or answer but it sounds to me replacing the carburetor may be the first step.
