The idle on my engine (O-360-A1A) is rough/erratic. If I try to idle at 650, it will run 630 to 680. I have a brand new Avstar carb, 10-3878, and have installed new rubber induction tube connections. One thought that I have is the Whirlwind 200RV prop has lower inertia than either a fixed pitch metal prop or a Hartzell CS prop. Could this be a reason? The carb I THINK is set up properly. The mixture screw is 1 1/2 turns out from full in, and while it is hard to tell because of the erratic idle, it looks like about a 50 RPM rise when I pull the mixture. The timing (Slicks) was just set at 25 deg, and the plugs were just cleaned and gapped. Any ideas? One other clue is when I am shooting touch and goes I smell a little gas when landing and then giving full power for take off. Maybe still too rich? Thanks
