What Does Live Engine Testing Involve?

RPM Pre-Set: We want to Make Sure The Carburetor Curb idle is Pre-Set, Not to Low and Not to High, A Low Curb Idle Setting will Leave the Engine Running Rough Causing a Poor Running Engine, However a High Idle will Leave the Engine Racing Causing a Rich Running Condition.  We Can Promise You the Curb Idle will be Set for a Plug-N-Play Setup.

Fast Idle Pre-Set: I can't Emphasize this Enough, Fast Idle or Idle at Cold Start has to be One of the More Important Adjustments on the Carburetor.  Everyone Has Started an Engine in the Morning, Idle Goes High, then Drops Down into Normal Operating Temperature.  However if the Fast Idle is Not Set Properly then the Fast Idle will not Drop or will Take Longer to Drop.  When We Pre-Set this Adjustment on Carburetor We Make Sure the Choke is Opening the Choke Valve Normally and Make all the Necessary Adjustments on Our Live Engine to leave the Carburetor Ready to Go.

Mixture idle Screws Pre-Set: Fuel Economy, Fuel Economy, Fuel Economy, That is Why We Pre-Set this Adjustment.  We Always want to Set the Carburetor to Run Clean, a Clean Running Engine is always a Better and Efficient Engine.  Air/Fuel Ratio is Crucial to a Good Running Carburetor.  If you Order a Carburetor from Us, I can Guarantee You the Carburetor Will  Run Smooth, Clean, and Have the Power there When You Need it!
