How big is the Nut in the Center of the Balancer

I can't remember myself. A tell: when you retard the timing (what you want to do), the idle will go down. Just be sure to make a mark where you have the timing set now (just a sharpie mark on the dizzy and lower intake works) if you dont have a timing light. That way you can hose around with the dizzy and get it back to where you are now.

Good luck Dan.
 
haha...yeah well its just not my week or few days...when I was about to chaning the timing...my timing light broke so...yeah...I know it is at 16 but there is not detenation but I still want to bump it down to 10 since I will be running the nitrous in like 2 weeks. Plus I am still pretty cautious about the whole install and everything....When i took it for a little ride before to see if it was working ok, I noticed a big difference from having underdrive pulleys to me putting the stock ones back on now. The car doesnt rev as fast as it normally would.
