Anybody? God, this set up takes the guess work out of wondering what your doing? At least look at the video~! You remove the jets out of the primary and secondary blocks and put the new block inbetween the float bowl and the original metering block...KEEP IT SIMPLE FOR STUPID~! Set the needle only finger tight, not crank it down with a torque wrench~! Then count off the required amount to get the original jets that were in the carb, then tune~! If you install the air/fuel gauge kit along with this, then you can literally tune on the fly~! Instead of the stop car, pull fuel bowls, read and replace jets, over and over and over and over, then claim the carb is messed up....Send back to Holley as they laugh at you for screwing up carb....Carb is then refurbished and sold on ebay where I buy carb and resell to next person...
Think about it..
I love capitalism and people that can't read instructions~!
