Congrats again on your purchase and welcome....
There isn't really any link for the test, George told me of a procedure using a flashlight to help determine if your primary and secondary blades are fully closed. All I did was turn out the lights, so that you have complete darkness and shine the flashlight through the front and back of each blade. Now as I have found out, this is more of a test for the secondary blades as opposed to the primary blade. Reason being as was mentioned to me, is that the primary blade does not close completely, so there will be light that does shine through on that blade.
Dominic has a procedure to check out the primary blade by using a thin piece of paper and see how much resistance you have pulling it through the bottom of the primary blade when in the closed position. It should pull through with resistance.
Just to be clear, at this point I am not sure or exactly know what is the cause of my idle issue. I will have to wait until everything is back together and even then I may not know the actual cause because I am making adjustments and checking everything out under the plenum, and the TB. If it still persists after, I would definitely lean towards the TB.
Hope this helps.....
