When I first bought my RV-6 (steam gauges & vacuum system) a few weeks ago, the first couple flights the suction gauge displayed normal, in the upper part of the green band (5-5.5 inches). The last flight I made this weekend, I noticed that at engine idle rpms, the suction gauge was showing about 7 inches, and as the rpms increased for takeoff and normal flight, it dropped back down to the upper green band, about 5.5 inches.
Is my vacuum regulator sticking or need adjustment? Is this the sign of a possibly clogged main inlet filter (it looks clean visually)? Or worse?
