Tuning the HSN and LSN
Well I accidentally changed the setting on my HSN recently. Now I am trying to retuned it. How can I figure out what setting is good for the HSN? What signs should i looke for? Rite now it is running smoothly but there is alot of unburned fuel coming out the pipe. How can i know that i am leaned it out enough?

if you lost track of your needles, go back to factory settings and tune it from there.
as long as the car performs well, don't worry too much about the temps. lean out the high speed, then tune the low until you're happy with it. then look at the temps and adjust your needles to makw the temps the way you want them.

Also, when tuning, like james said do the HSN first. Make sure you the engine is running good at high speed and make sure there is a nice streak of exaust smoke coming from your pipe. If there's NO smoke, that's a good sign you're not getting enough fuel too. You always want some smoke at full throttle.

once you have leaned it out to the max PERFORMANCE, check the temp and richen it until you feel comfortable with the temp. I like to run my engines a little hotter than most people. most will say to run your engine at 220, but i like to run mine at 230 and a little higher, depending on the weather (hotter the day, hotter i run the engine. the colder, the colder i'll run the engine).
for the low speed, lean it out to where you pinch the fuel line a few inches before the carb and it dies out after 3 seconds (the engine should rev up a little then die. if it just dies, too lean. if it takes a looooooooooong time to die, too rich).
good luck!
