Aaron:

You might want to check those bypass valves.  There's a good chance you've 
got a large vacuum leak which will cause a very high idle.  Even after I 
rebuil my cars I had to block the valves off completely on my '69 TR6 in 
order to bring the idle down to a manageable level.  It sure sounds like a 
vacuum problem somewhere.

Good luck,
Walt Fogle
