Tuning, okay then...
Basically, with the highspeed needle, you set it first...
once you've been DRIVING for about 1 minute, watch how the car performs... does it flat spot with a lot of smoke?
does it falter with no smoke, does it rev right out but have no smoke?
Does it rev out nicely with a small slight trail of smoke from the stinger?
You want the last one for a good high end tune...
Now a low end tune...
Drive in, stop, and about 3 seconds later gun it off the mark... does it falter? does it come off the line crisp and fast? or does it bog down and nearly die?
Slowly adjust the low speed needle until it comes off the line crisp and fast...
the idle speed...
once the main and low speed needle are set, drive around, and slow down slowly (coast in) and stop, (dont use the brakes)
Does the car keep driving forwards? Yes? well then turn the idle screw (small one with spring) so the revs drop... but remember, each adjustment, drive off a bit and come back... it allows the carb opening to settle in...
After each mixture change, allow about 30seconds to 1 minute to see the full change...
Set the idle so the motor is running fast enough to not die, and slow enough so the car doesnot move, or only bumps slightly forward once in a while
