First turn on your truck and remote,(engine not running) hit the gas then release. then check your servo position at neutral(after you let go), the arm on your carb should be as far back as it goes, and your brakes should not be applied at all. Adjustments to your idle should be done now. I would close your idle to 1-2 mm(about 1/16"). Things can get tricky if you adjust your other needles before properly adjusting your idle. you end up making the mixture to rich or too lean to compensate for the high or low idle.

2 1/2 on the hsn is a good setting for a new motor.
Where in ontario are you??

Good luck,
