Carb Idle Tuning and Vacuum - 02/13/12 03:37 PM
I'm trying to tune the idle air mixture on my eddy 750 and am going off of the vacuum method. I turn the screws CW or CCW until highest vacuum is achieved. It doesn't appear that the engine changes much, maybe 2 lbs in either direction. My highest vacuum reading is 16.
Is this a good reading for a stock built 440 with a 268/454 cam?
Should I be seeing more than just a 2 lb drop with adjusting the screws either full in or full out? I don't hear too much of a chane in the RPM. For tuning purposes I've cranked the RPM to 850.
Thanks
