What can cause an uneven air volume reading while adjusting the idle on 48 IDA's? Yesterday the air volume between throats on a single carb was uneven. Throttle plates are phased the same. Compression is the same throughout the engine, valves adjusted. Gaskets were checked and are not compromised. The mixture screw for the cylinder in question has no impact on runability. I realize this is a question of High Pressure (above the throttle plate)/Low Pressure (below the throttle plate) why are the two runners different if they are opened at the same moment & rate.
If a plug fouls will that impact the indicated flow?
What am I overlooking? I'm thinking too hard on this.
