A reason it gets worse wit h the cowling on is that there is warmer air inside the cowling. Without t he cowling the surrounding air stays the same temp. May I suggest you get a spray water bottle. With the engine running=2C carefully spray all the i ntake connections and see what happens. If there is an intake leak the eng ine should stutter. If that does not work give me a call. I think you sti ll have my cell phone number. Also=2C we are flying down to your neck of th e woods on january 10th for a week in Orlando at out timeshare. maybe we c an get together.

The intake leak seems to be a big "seller" and I'm getting a bit of feedback on wood propellers causing idle problems on the big four cyl Lycomings, especially with fuel injection installed. Wish I'd known this sooner and I would have opted for the Sensenich fixed pitch but it's nice to have all you folks out there with your collective knowledge to get me going in the right direction. If anyone else has some more thoughts please forward them to me so I can check all possibilities. If everything checks out ok and there are no engine related culprits, I've decided I'll take the plunge and order a Sensenich prop. Problem is that it takes several weeks to get one and I don't really want to wait. So...does anyone already have a Sensenich prop and spacer laying around that they won't be using for a few months(for 180 HP Lyc 0-360)? If so maybe I could purchase it from you and have the one I order shipped to you when it's ready. Just thinking ahead. Also, if I go ahead with the metal prop, I'll be selling my 70x82 Sterba wood prop (carved in 2006), spacer, crush plate, Landoll inertia ring and fitted spinner (painted silver) so if anyone wants a wood prop for 0-360 Lyc let me know and we'll work out a price for all or part of the assembly. Thanks.

I have a wood prop on an O-360 and no problems like you are having. I would find a competent mechanic to help first.

What is the idle speed of your engine? If it is below 700 RPM, it might be a factor.
