I have two "super" venturis plumbed in parallel, running two modern (non-AN) gyros, with a vacuum regulator. I get 4" Hg suction on the takeoff roll and 5" at all speeds over 60 mph. I don't know how much I'd get without a regulator. I used to have just one venturi but it wasn't ...

The hoses lay flat. You just have to watch for chafing where they come close to stringer/stiffener flanges.

The -0100 means they're 10 inches long, measured between sealing flats.

No, same part number for both. Fig 58, index 4.

ADSB is very helpful on the Ripon-Fisk arrival. Of course I’m looking out the window, but an occasional glance at the iPad helps to assure me that I’m not missing someone.

Good decision to stay with the stock seats if you can. My airplane has seats from a 1975 172 that cause all kinds of problems. I adjusted their heights when I bought the airplane 15 years ago and haven’t touched them since!

I'm very happy with my MT and glad to be rid of the old Hartzell. The change took off 10 pounds and added a lot to my rate of climb.

Empty weight is 1393 lb., calculated from a weighing in 1993. Avcon O-360, front seats from a '75 172, back seats, and full interior.

The eddy current inspection AD on that Hartzell prop hub is a real pain, especially if you don't have a shop nearby that can do it. Before I got rid of my Hartzell I was paying $300 every 100 hours for the inspection.

Looks to me like the stall warn unit is below the pilot side yoke.

I’ve never seen a Brackett filter clogged. What do you see?

Aero Prop at KBJC in the Denver area does eddy current inspections.

Nothing organized (yet), but Sunday night before the show the camping area will be full of us 170 types!

Has anyone used the approved screws to attach the seat rails rather than rivets as advertised at McFarlane Aviation when replacing seat rails? I have used screws for the larger diameter fasteners at the ends of the rails. You just have to spot-face the locations on the rail to make sure the screw h...

40 years ago one of my first owner maintenance tasks I took on on my new to me run out '67 Cherokee with Lycoming 0-320, was "the wobble " test. Valve guide clearance failed. At 2200 hrs the fit was to loose. (not the intended reason to do the test). After removing the cylinder I decided ...

The heck you say!
