Default NITRO TUNNING (PINCH TEST)

Getting back into the nitro stuff again and what are some key things to remember when tuning. I remember something about a pinch test to set you low speed needle? Sound familiar. Any help

If you pinch your fuel line it should rev up then die within 3-5 seconds then it means your lowend is set.
If it dies before the 3-5 seconds then your too lean.
If it dies after the 3-5 seconds then your too rich.

Pinch test is not 100% accurate. It is however a good guide to get close. All motors are not the same with the pinch test.
